Commit 9d311e11fc1f ("Btrfs: fiemap: pass correct bytenr when
fm_extent_count is zero") introduced a regression where we no longer
report 0 as the physical offset for inline extents (and other extents
with a special block_start value). This is because it always sets the
variable used to report the physical offset ("disko") as em->block_start
plus some offset, and em->block_start has the value 18446744073709551614
((u64) -2) for inline extents.
This made the btrfs test 004 (from fstests) often fail, for example, for
a file with an inline extent we have the following items in the subvolume
tree:
item 101 key (418 INODE_ITEM 0) itemoff 11029 itemsize 160
generation 25 transid 38 size 1525 nbytes 1525
block group 0 mode 100666 links 1 uid 0 gid 0 rdev 0

mtime 1529342058.461891730 (2018-06-18 18:14:18)
otime 1529342055.869892885 (2018-06-18 18:14:15)

generation 38 type 0 (inline)
inline extent data size 1525 ram_bytes 1525 compression 0 (none)
Then when test 004 invoked fiemap against the file it got a non-zero
physical offset:
$ filefrag -v /mnt/p0/d4/d7/fc7
Filesystem type is: 9123683e
File size of /mnt/p0/d4/d7/fc7 is 1525 (1 block of 4096 bytes)

This resulted in the test failing like this:

The large number in scientific notation reported as an invalid numeric
value is the result from the filter passed to perl which multiplies the
physical offset by the block size reported by fiemap.
So fix this by ensuring the physical offset is always set to 0 when we
are processing an extent with a special block_start value.

In two places, the gfs2_io_error_bh macro is called while holding the
sd_ail_lock spin lock. This isn't allowed because gfs2_io_error_bh
withdraws the filesystem, which can sleep because it issues a uevent.
To fix that, add a gfs2_io_error_bh_wd macro that does withdraw the
filesystem and change gfs2_io_error_bh to not withdraw the filesystem.
In those places where the new gfs2_io_error_bh is used, withdraw the
filesystem after releasing sd_ail_lock.

Before this patch, block reservations kept track of the inode
number. At one point, that was a valid thing to do. However, since
we made the reservation a part of the inode (rather than a pointer
to a separate allocated object) the reservation can determine the
inode number by using container_of. This saves us a little memory
in our inode.

While __atomic_add_unless() was originally intended as a building-block
for atomic_add_unless(), it's now used in a number of places around the
kernel. It's the only common atomic operation named __atomic*(), rather
than atomic_*(), and for consistency it would be better named
atomic_fetch_add_unless().
This lack of consistency is slightly confusing, and gets in the way of
scripting atomics. Given that, let's clean things up and promote it to
an official part of the atomics API, in the form of
atomic_fetch_add_unless().
This patch converts definitions and invocations over to the new name,
including the instrumented version, using the following script:
----
git grep -w __atomic_add_unless | while read line; do
sed -i '{s/\<__atomic_add_unless\>/atomic_fetch_add_unless/}' "${line%%:*}";
done
git grep -w __arch_atomic_add_unless | while read line; do
sed -i '{s/\<__arch_atomic_add_unless\>/arch_atomic_fetch_add_unless/}' "${line%%:*}";
done
----
Note that we do not have atomic{64,_long}_fetch_add_unless(), which will
be introduced by later patches.
There should be no functional change as a result of this patch.

For now just limited to blocksize == PAGE_SIZE, where we can simply read
in the full page in write begin, and just set the whole page dirty after
copying data into it. This code is enabled by default and XFS will now
be feed pages without buffer heads in ->writepage and ->writepages.
If a file system sets the IOMAP_F_BUFFER_HEAD flag on the iomap the old
path will still be used, this both helps the transition in XFS and
prepares for the gfs2 migration to the iomap infrastructure.

The rewrite of the cmdline fetching missed the fact that we used to also
return the final terminating NUL character of the last argument. I
hadn't noticed, and none of the tools I tested cared, but something
obviously must care, because Michal Kubecek noticed the change in
behavior.
Tweak the "find the end" logic to actually include the NUL character,
and once past the eend of argv, always start the strnlen() at the
expected (original) argument end.
This whole "allow people to rewrite their arguments in place" is a nasty
hack and requires that odd slop handling at the end of the argv array,
but it's our traditional model, so we continue to support it.

Add generic inline data handling by adding a pointer to the inline data
region to struct iomap. When handling a buffered IOMAP_INLINE write,
iomap_write_begin will copy the current inline data from the inline data
region into the page cache, and iomap_write_end will copy the changes in
the page cache back to the inline data region.
This doesn't cover inline data reads and direct I/O yet because so far,
we have no users.

According to xfstest generic/240, applications seem to expect direct I/O
writes to either complete as a whole or to fail; short direct I/O writes
are apparently not appreciated. This means that when only part of an
asynchronous direct I/O write succeeds, we can either fail the entire
write, or we can wait for the partial write to complete and retry the
remaining write as buffered I/O. The old __blockdev_direct_IO helper
has code for waiting for partial writes to complete; the new
iomap_dio_rw iomap helper does not.
The above mentioned fallback mode is needed for gfs2, which doesn't
allow block allocations under direct I/O to avoid taking cluster-wide
exclusive locks. As a consequence, an asynchronous direct I/O write to
a file range that contains a hole will result in a short write. In that
case, wait for the short write to complete to allow gfs2 to recover.

The file creation time in the inode uses time_t which is defined
differently on 32-bit and 64-bit architectures and deprecated. The
representation in the inode uses an unsigned 32-bit number, but this
gets wrapped around after year 2038 when assigned to a time_t.
This changes the type to time64_t, so we can support the full range of
timestamps between 1970 and 2106 on 32-bit systems like we do on 64-bit
systems already, and matching what we do for the atime/ctime/mtime stamps
since the introduction of 64-bit timestamps in VFS.
Note: the otime stamp is not actually used anywhere at the moment in
the kernel, it is just set when writing a file, so none of this really
makes a difference unless we implement setting the btime field in the
getattr() callback.

Commit 30181faae37f ("nfsd: Check queue type before submitting a SCSI

request queue that won't support them, but that check is in the
GETDEVICEINFO path. Let's not set the SCSI layout in fs_layout_type in the
first place, and then we'll have less clients sending GETDEVICEINFO for
non-SCSI request queues and less unnecessary WARN_ONs.
While we're in here, remove some outdated comments that refer to

This patch replaces the ib_device_attr.max_sge with max_send_sge and
max_recv_sge. It allows ulps to take advantage of devices that have very
different send and recv sge depths. For example cxgb4 has a max_recv_sge
of 4, yet a max_send_sge of 16. Splitting out these attributes allows
much more efficient use of the SQ for cxgb4 with ulps that use the RDMA_RW
API. Consider a large RDMA WRITE that has 16 scattergather entries.
With max_sge of 4, the ulp would send 4 WRITE WRs, but with max_sge of
16, it can be done with 1 WRITE WR.

The kernel's ext4 mount-time checks were more permissive than
e2fsprogs's libext2fs checks when opening a file system. The
superblock is considered too insane for debugfs or e2fsck to operate
on it, the kernel has no business trying to mount it.
This will make file system fuzzing tools work harder, but the failure
cases that they find will be more useful and be easier to evaluate.

Pull fsnotify updates from Jan Kara:
"fsnotify cleanups unifying handling of different watch types.
This is the shortened fsnotify series from Amir with the last five
patches pulled out. Amir has modified those patches to not change
struct inode but obviously it's too late for those to go into this
merge window"
* tag 'fsnotify_for_v4.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs:
fsnotify: add fsnotify_add_inode_mark() wrappers
fanotify: generalize fanotify_should_send_event()
fsnotify: generalize send_to_group()
fsnotify: generalize iteration of marks by object type
fsnotify: introduce marks iteration helpers
fsnotify: remove redundant arguments to handle_event()
fsnotify: use type id to identify connector object type

When expanding the extra isize space, we must never move the
system.data xattr out of the inode body. For performance reasons, it
doesn't make any sense, and the inline data implementation assumes
that system.data xattr is never in the external xattr block.
This addresses CVE-2018-10880
