This exists internal to ctree.c, however btrfs check needs to use it for
some of its operations. I'd rather not duplicate that code inside of
btrfs check as this is low level and I want to keep this code in one
place, so rename the function to btrfs_del_ptr and export it so that it
can be used inside of btrfs-progs safely. Add a comment to make sure
this doesn't get removed by a future cleanup.

This is needed in btrfs-progs for the tools that convert the checksum
types for file systems and a few other things. We don't have it in the
kernel as we just want to get the size for the super blocks type.
However I don't want to have to manually add this every time we sync
ctree.c into btrfs-progs, so add the helper in the kernel with a note so
it doesn't get removed by a later cleanup.

This helper returns a btrfs_tree_block_status for the various errors,
and then btrfs_check_node() will return -EUCLEAN if it gets anything
other than BTRFS_TREE_BLOCK_CLEAN which will be used by the kernel. In
the future btrfs-progs will use this helper instead.

Instead of blanket returning -EUCLEAN for all the failures in
btrfs_check_leaf, use btrfs_tree_block_status and return the appropriate
status for each failure. Rename the helper to __btrfs_check_leaf and
then make a wrapper of btrfs_check_leaf that will return -EUCLEAN to
non-clean error codes. This will allow us to have the
__btrfs_check_leaf variant in btrfs-progs while keeping the behavior in
the kernel consistent.

We use this in btrfs-progs to determine if we can fix different types of
corruptions. We don't care about this in the kernel, however it would
be good to share this code between the kernel and btrfs-progs, so add
the status definitions so we can start converting the tree-checker code
over to using these status flags instead of blanket returning -EUCLEAN.

We have two helpers for checking leaves, because we have an extra check
for debugging in btrfs_mark_buffer_dirty(), and at that stage we may
have item data that isn't consistent yet. However we can handle this
case internally in the helper, if BTRFS_HEADER_FLAG_WRITTEN is set we
know the buffer should be internally consistent, otherwise we need to
skip checking the item data.
Simplify this helper down a single helper and handle the item data
checking logic internally to the helper.

For P/Q stripe scrub, we have quite some duplicated read IO:
- Data stripes read for verification
This is triggered by the scrub_submit_initial_read() inside
scrub_raid56_parity_stripe().
- Data stripes read (again) for P/Q stripe verification
This is triggered by scrub_assemble_read_bios() from scrub_rbio().
Although we can have hit rbio cache and avoid unnecessary read, the
chance is very low, as scrub would easily flush the whole rbio cache.
This means, even we're just scrubbing a single P/Q stripe, we would read
the data stripes twice for the best case scenario. If we need to
recover some data stripes, it would cause more reads on the same data
stripes, again and again.
However before we call raid56_parity_submit_scrub_rbio() we already
have all data stripes repaired and their contents ready to use.
But RAID56 cache is unaware about the scrub cache, thus RAID56 layer
itself still needs to re-read the data stripes.
To avoid such cache miss, this patch would:
- Introduce a new helper, raid56_parity_cache_data_pages()
This function would grab the pages from an array, and copy the content
to the rbio, marking all the involved sectors uptodate.
The page copy is unavoidable because of the cache pages of rbio are all
self managed, thus can not utilize outside pages without screwing up
the lifespan.
- Use the repaired data stripes as cache inside
scrub_raid56_parity_stripe()
By this, we ensure all the data sectors of the scrub rbio are already
uptodate, and no need to read them again from disk.

Removing a free space entry from an in memory space cache requires having
the corresponding btrfs_free_space_ctl's 'tree_lock' held. We have several
code paths that remove an entry, so add assertions where appropriate to
verify we are holding the lock, as the lock is acquired by some other
function up in the call chain, which makes it easy to miss in the future.
Note: for this to work we need to lock the local btrfs_free_space_ctl at
load_free_space_cache(), which was not being done because it's local,
declared on the stack, so no other task has access to it.

When linking a free space entry, at link_free_space(), the caller should
be holding the spinlock 'tree_lock' of the given btrfs_free_space_ctl
argument, which is necessary for manipulating the red black tree of free
space entries (done by tree_insert_offset(), which already asserts the
lock is held) and for manipulating the 'free_space', 'free_extents',
'discardable_extents' and 'discardable_bytes' counters of the given
struct btrfs_free_space_ctl.
So assert that the spinlock 'tree_lock' of the given btrfs_free_space_ctl
is held by the current task. We have multiple code paths that end up
calling link_free_space(), and all currently take the lock before calling
it.

since they do other things that require those locks to be held. This makes

At copy_free_space_cache(), we add a new entry to the block group's ctl
before we free the entry from the temporary ctl. Adding a new entry
requires the allocation of a new struct btrfs_free_space, so we can
avoid a temporary extra allocation by freeing the entry from the
temporary ctl before we add a new entry to the main ctl, which possibly
also reduces the chances for a memory allocation failure in case of very
high memory pressure. So just do that.

[PROBLEM]
When relocation fails (mostly due to checksum mismatch), we only got
very cryptic error messages like:
BTRFS info (device dm-4): relocating block group 13631488 flags data
BTRFS warning (device dm-4): csum failed root -9 ino 257 off 0 csum 0x373e1ae3 expected csum 0x98757625 mirror 1
BTRFS error (device dm-4): bdev /dev/mapper/test-scratch1 errs: wr 0, rd 0, flush 0, corrupt 1, gen 0
BTRFS info (device dm-4): balance: ended with status: -5
The end user has to decipher the above messages and use various tools to
locate the affected files and find a way to fix the problem (mostly
deleting the file). This is not an easy work even for experienced
developer, not to mention the end users.
[SCRUB IS DOING BETTER]
By contrast, scrub is providing much better error messages:
BTRFS error (device dm-4): unable to fixup (regular) error at logical 13631488 on dev /dev/mapper/test-scratch1 physical 13631488
BTRFS warning (device dm-4): checksum error at logical 13631488 on dev /dev/mapper/test-scratch1, physical 13631488, root 5, inode 257, offset 0, length 4096, links 1 (path: file)
BTRFS info (device dm-4): scrub: finished on devid 1 with status: 0
Which provides the affected files directly to the end user.
[IMPROVEMENT]
Instead of the generic data checksum error messages, which is not doing
a good job for data reloc inodes, this patch introduce a scrub like
backref walking based solution.
When a sector fails its checksum for data reloc inode, we go the
following workflow:
- Get the real logical bytenr
For data reloc inode, the file offset is the offset inside the block
group.
Thus the real logical bytenr is @file_off + @block_group->start.
- Do an extent type check
If it's tree blocks it's much easier to handle, just go through
all the tree block backref.
- Do a backref walk and inode path resolution for data extents
This is mostly the same as scrub.
But unfortunately we can not reuse the same function as the output
format is different.
Now the new output would be more user friendly:
BTRFS info (device dm-4): relocating block group 13631488 flags data
BTRFS warning (device dm-4): csum failed root -9 ino 257 off 0 logical 13631488 csum 0x373e1ae3 expected csum 0x98757625 mirror 1
BTRFS warning (device dm-4): checksum error at logical 13631488 mirror 1 root 5 inode 257 offset 0 length 4096 links 1 (path: file)
BTRFS error (device dm-4): bdev /dev/mapper/test-scratch1 errs: wr 0, rd 0, flush 0, corrupt 2, gen 0
BTRFS info (device dm-4): balance: ended with status: -5

The writeback_control structure already passes down the information about
a writeback being synchronous from the core VM code, and thus information
is propagated into the bio REQ_SYNC flag through the wbc_to_write_flags
helper.
Use that information to decide if checksums calculation is offloaded to
a workqueue instead of btrfs_inode::sync_writers field that not only
bloats the inode but also has too wide scope, being inode wide instead
of limited to the actual writeback request.
The sync writes were set in:
- btrfs_do_write_iter - regular IO, sync status is set
- start_ordered_ops - ordered write start, writeback with WB_SYNC_ALL
mode
- btrfs_write_marked_extents - write marked extents, writeback with

Most modern hardware supports very fast accelerated crc32c calculation.
If that is supported the CPU overhead of the checksum calculation is
very limited, and offloading the calculation to special worker threads
has a lot of overhead for no gain.
E.g. on an Intel Optane device is actually very much slows down even
1M buffered writes with fio:
Unpatched:
write: IOPS=3316, BW=3316MiB/s (3477MB/s)(200GiB/61757msec); 0 zone resets
With synchronous CRCs:
write: IOPS=4882, BW=4882MiB/s (5119MB/s)(200GiB/41948msec); 0 zone resets
With a lot of variation during the unpatched run going down as low as
1100MB/s, while the synchronous CRC version has about the same peak write
speed but much lower dips, and fewer kworkers churning around.
Both tests had fio saturated at 100% CPU.

When checking siblings keys, before moving keys from one node/leaf to a
sibling node/leaf, it's very unexpected to have the last key of the left
sibling greater than or equals to the first key of the right sibling, as
that means we have a (serious) corruption that breaks the key ordering
properties of a b+tree. Since this is unexpected, surround the comparison
with the unlikely macro, which helps the compiler generate better code
for the most expected case (no existing b+tree corruption). This is also
what we do for other unexpected cases of invalid key ordering (like at
btrfs_set_item_key_safe()).

Recently a Meta-internal workload encountered subvolume creation taking
up to 2s each, significantly slower than directory creation. As they
were hoping to be able to use subvolumes instead of directories, and
were looking to create hundreds, this was a significant issue. After
Josef investigated, it turned out to be due to the transaction commit
currently performed at the end of subvolume creation.
This change improves the workload by not doing transaction commit for every
subvolume creation, and merely requiring a transaction commit on fsync.
In the worst case, of doing a subvolume create and fsync in a loop, this
should require an equal amount of time to the current scheme; and in the
best case, the internal workload creating hundreds of subvolumes before
fsyncing is greatly improved.
While it would be nice to be able to use the log tree and use the normal
fsync path, log tree replay can't deal with new subvolume inodes
presently.
It's possible that there's some reason that the transaction commit is
necessary for correctness during subvolume creation; however,
git logs indicate that the commit dates back to the beginning of
subvolume creation, and there are no notes on why it would be necessary.

The driver overrides the error codes returned by platform_get_irq() to
-EINVAL, so if it returns -EPROBE_DEFER, the driver will fail the probe
permanently instead of the deferred probing. Switch to propagating the
error codes upstream.

The driver overrides the error codes and IRQ0 returned by platform_get_irq()
to -EINVAL, so if it returns -EPROBE_DEFER, the driver will fail the probe
permanently instead of the deferred probing. Switch to propagating the error
codes upstream. Since commit ce753ad1549c ("platform: finally disallow IRQ0
in platform_get_irq() and its ilk") IRQ0 is no longer returned by those APIs,
so we now can safely ignore it...

mmc host drivers should have enabled the asynchronous probe option, but
it seems like we didn't set it for litex_mmc when introducing litex mmc
support, so let's set it now.
Tested with linux-on-litex-vexriscv on sipeed tang nano 20K fpga.
