For certain platforms, it may necessary to use the STEP in URM
(ultra reliable mode.) Read the necessary flags from the BIOS
(ACPI or UEFI) and indicate the chosen mode to the firmware in
the context info. Whether or not URM really was configured is
already read back later, to adjust capabilities accordingly.

This variable exists for the "common" (WiFi/BT) GUID, not the
WiFi-only GUID. Fix that by passing the GUID to the function.
A short-cut for the wifi-only version remains so not all code
must be updated.
However, rename the GUID defines to be clearer.

[BUG]
When running btrfs with block size (4K) smaller than page size (64K,
aarch64), there is a very high chance to crash the kernel at
generic/750, with the following messages:
(before the call traces, there are 3 extra debug messages added)

[CAUSE]
The above warning is triggered immediately after the delalloc range
failure, this happens in the following sequence:
- Range [1568K, 1636K) is dirty
1536K 1568K 1600K 1636K 1664K
| |/////////|////////| |
Where 1536K, 1600K and 1664K are page boundaries (64K page size)
- Enter extent_writepage() for page 1536K
- Enter run_delalloc_nocow() with locked page 1536K and range
[1568K, 1636K)
This is due to the inode having preallocated extents.
- Enter cow_file_range() with locked page 1536K and range
[1568K, 1636K)
- btrfs_reserve_extent() only reserved two extents
The main loop of cow_file_range() only reserved two data extents,
Now we have:
1536K 1568K 1600K 1636K 1664K
| |<-->|<--->|/|///////| |
1584K 1596K
Range [1568K, 1596K) has an ordered extent reserved.
- btrfs_reserve_extent() failed inside cow_file_range() for file offset
1596K
This is already a bug in our space reservation code, but for now let's
focus on the error handling path.
Now cow_file_range() returned -ENOSPC.
- btrfs_run_delalloc_range() do error cleanup <<< ROOT CAUSE
Call btrfs_cleanup_ordered_extents() with locked folio 1536K and range
[1568K, 1636K)
Function btrfs_cleanup_ordered_extents() normally needs to skip the
ranges inside the folio, as it will normally be cleaned up by
extent_writepage().
Such split error handling is already problematic in the first place.
What's worse is the folio range skipping itself, which is not taking
subpage cases into consideration at all, it will only skip the range
if the page start >= the range start.
In our case, the page start < the range start, since for subpage cases
we can have delalloc ranges inside the folio but not covering the
folio.
So it doesn't skip the page range at all.
This means all the ordered extents, both [1568K, 1584K) and
[1584K, 1596K) will be marked as IOERR.
And these two ordered extents have no more pending ios, they are marked
finished, and *QUEUED* to be deleted from the io tree.
- extent_writepage() do error cleanup
Call btrfs_mark_ordered_io_finished() for the range [1536K, 1600K).
Although ranges [1568K, 1584K) and [1584K, 1596K) are finished, the
deletion from io tree is async, it may or may not happen at this
time.
If the ranges have not yet been removed, we will do double cleaning on
those ranges, triggering the above ordered extent warnings.
In theory there are other bugs, like the cleanup in extent_writepage()
can cause double accounting on ranges that are submitted asynchronously
(compression for example).
But that's much harder to trigger because normally we do not mix regular
and compression delalloc ranges.
[FIX]
The folio range split is already buggy and not subpage compatible, it
was introduced a long time ago where subpage support was not even considered.
So instead of splitting the ordered extents cleanup into the folio range
and out of folio range, do all the cleanup inside writepage_delalloc().
- Pass @NULL as locked_folio for btrfs_cleanup_ordered_extents() in
btrfs_run_delalloc_range()
- Skip the btrfs_cleanup_ordered_extents() if writepage_delalloc()
failed
So all ordered extents are only cleaned up by
btrfs_run_delalloc_range().
- Handle the ranges that already have ordered extents allocated
If part of the folio already has ordered extent allocated, and
btrfs_run_delalloc_range() failed, we also need to cleanup that range.
Now we have a concentrated error handling for ordered extents during
btrfs_run_delalloc_range().

Current ASoC is using dai_link->dai_fmt to set DAI format for both
CPU/Codec. But because it is using same settings, and
SND_SOC_DAIFMT_CLOCK_PROVIDER is flipped for CPU, we can't set both
CPU/Codec as clock consumer, for example.

The source static analysis tool gave the following advice:
./fs/xfs/libxfs/xfs_dir2.c:382:15-22: WARNING opportunity for kmemdup
→ 382 args->value = kmalloc(len,
383 GFP_KERNEL | __GFP_NOLOCKDEP | __GFP_RETRY_MAYFAIL);

385 return -ENOMEM;
386
→ 387 memcpy(args->value, name, len);
388 args->valuelen = len;
389 return -EEXIST;
Replacing kmalloc() + memcpy() with kmemdump() doesn't change semantics.
Original code works without fault, so this is not a bug fix but proposed improvement.

The b_error check right after xfs_trans_get_buf() is redundant:
1) If the buffer is found in transaction via xfs_trans_buf_item_match(),
any corrupted metadata error would have already been exposed during
previous reads like xfs_da3_node_read().
2) If the buffer is obtained via xfs_buf_get_map():
- It's called without XBF_READ flag, so won't return buffer with
b_error set, since xfs_buf_get_map() will clear it anyway.
- Buffer found in cache normally won't have error since previous reads
had checked it, unless someone corrupts the buffer and the AIL
pushes it out to disk while the buffer's unlocked. But in this case,
AIL will shut down the log.
Remove this redundant check to simplify the code, make the code consistent
with most other xfs_trans_get_buf() callers in XFS.

During log recovery, while updating the in-memory superblock from the
primary SB buffer, if an error is encountered, such as superblock
corruption occurs or some other reasons, we will proceed to out_release
and release the xfs_buf. However, this is insufficient because the
xfs_buf's log item has already been initialized and the xfs_buf is held
by the buffer log item as follows, the xfs_buf will not be released,
causing the mount thread to hang.
xlog_recover_do_primary_sb_buffer
xlog_recover_do_reg_buffer
xlog_recover_validate_buf_type
xfs_buf_item_init(bp, mp)
The solution is straightforward, we simply need to allow it to be
handled by the normal buffer write process. The filesystem will be
shutdown before the submission of buffer_list in xlog_do_recovery_pass(),
ensuring the correct release of the xfs_buf as follows:
xlog_do_recovery_pass
error = xlog_recover_process
xlog_recover_process_data
xlog_recover_process_ophdr
xlog_recovery_process_trans
...
xlog_recover_buf_commit_pass2

//Encounter error and return
if (error)
goto out_writebuf
...

return error
...
if (!list_empty(&buffer_list))
if (error)
xlog_force_shutdown(log, SHUTDOWN_LOG_IO_ERROR); //shutdown first
xfs_buf_delwri_submit(&buffer_list); //submit buffers in list

xfs: reflink on the realtime device [v6.2 05/14]
This patchset enables use of the file data block sharing feature (i.e.
reflink) on the realtime device. It follows the same basic sequence as
the realtime rmap series -- first a few cleanups; then introduction of
the new btree format and inode fork format. Next comes enabling CoW and
remapping for the rt device; new scrub, repair, and health reporting
code; and at the end we implement some code to lengthen write requests
so that rt extents are always CoWed fully.
This has been running on the djcloud for months with no problems. Enjoy!

xfs: realtime reverse-mapping support [v6.2 04/14]
This is the latest revision of a patchset that adds to XFS kernel
support for reverse mapping for the realtime device. This time around
I've fixed some of the bitrot that I've noticed over the past few
months, and most notably have converted rtrmapbt to use the metadata
inode directory feature instead of burning more space in the superblock.
At the beginning of the set are patches to implement storing B+tree
leaves in an inode root, since the realtime rmapbt is rooted in an
inode, unlike the regular rmapbt which is rooted in an AG block.
Prior to this, the only btree that could be rooted in the inode fork
was the block mapping btree; if all the extent records fit in the
inode, format would be switched from 'btree' to 'extents'.
The next few patches enhance the reverse mapping routines to handle
the parts that are specific to rtgroups -- adding the new btree type,
adding a new log intent item type, and wiring up the metadata directory
tree entries.
Finally, implement GETFSMAP with the rtrmapbt and scrub functionality
for the rtrmapbt and rtbitmap and online fsck functionality.
This has been running on the djcloud for months with no problems. Enjoy!

xfs: enable in-core block reservation for rt metadata [v6.2 03/14]
In preparation for adding reverse mapping and refcounting to the
realtime device, enhance the metadir code to reserve free space for
btree shape changes as delayed allocation blocks.
This enables us to pre-allocate space for the rmap and refcount btrees
in the same manner as we do for the data device counterparts, which is
how we avoid ENOSPC failures when space is low but we've already
committed to a COW operation.
This has been running on the djcloud for months with no problems. Enjoy!

Commit 449813515d3e ("block, fs: Restore the per-bio/request data
lifetime fields") restored write-hint support in btrfs. But that is
applicable only for direct IO. This patch supports passing
write-hint for buffered IO from btrfs file system to block layer
by filling bi_write_hint of struct bio in alloc_new_bio().
There's an ongoing discussion which devices can use that,
https://lore.kernel.org/all/20240910150200.6589-6-joshi.k@samsung.com,
in SCSI there's support using sd_group_number() and
sd_setup_rw32_cmnd().
The hint goes from the application directly to the block device so it's
up to the application to set up everything properly to utilize the
different hint classes.
