XFS had a bug that resulted in an unexpected NULL buffer during
unlink of an inode with a multi-level attr fork tree. This occurred
due to a stale reference to content in a released/reclaimed buffer.
Use the XFS buffer LRU reference count error injection tag to
recreate the conditions for the bug. Create a file with a
multi-level attr fork tree and then unlink it with buffer caching
disabled.
Commit f35c5e10c6ed ("xfs: reinit btree pointer on attr tree
inactivation walk") fixed the bug.

This commit adds a test to verify consistent d_ino feature when
the overlayfs instance is composed of two different underlying
filesystem instances.
For example,
$ mount -t xfs /dev/loop0 /mnt/test
$ mount -t xfs /dev/loop1 /mnt/scratch
$ mkdir /mnt/scratch/upper
$ mkdir /mnt/scratch/work
$ mount -t overlay overlay -o lowerdir=/mnt/test \
-o upperdir=/mnt/scratch/upper \
-o workdir=/mnt/scratch/work /mnt/merge
The goal of this test is to verify that the inode numbers returned by
readdir(3) (i.e. dirent->d_ino) are consistent with inode numbers
returned by stat(2) (i.e. stat->st_ino) in all the below listed cases,
- Parent's (i.e. "..") d_ino must always be calculated because a
pure dir can be residing inside a merged dir.
- d_ino for "." must always be calculated because the present
directory can have a copy-up origin.
- Verify d_ino of '.' and '..' before and after dir becomes impure.
While at it also verify if trusted.overlay.impure xattr is
set/reset appropriately and invalidation of readdir cache.
- Verify copied up file's (inside a impure dir) d_ino.
- Verify invalidation of readdir cache.
- Verify d_ino values corresponding to "." and ".." entries of a
pure lower dir.
- Verify d_ino of ".." entry of a merged dir.
- Verify pure lower residing in dir which has another lower layer

With upstream commit 332391a9935d ("fs: Fix page cache inconsistency
when mixing buffered and AIO DIO"), ext4 (and probably other
non-iomap based filesystems) need a _check_dmesg() whitelist entry
for a new WARN in dio_complete() -- generic/095 and 247 trigger a
dio_complete() splat pretty reliably for me.
Add dio_complete() entry to _filter_xfs_dmesg(), rename it and use
it unconditionally in generic/095, 224, 247 and 446.

generic/166 is takes way too long to run on iscsi disks - over an
*hour* on flash based iscsi targets. In comparison, it takes 18s to
run on a pmem device.
The issue is that it takes 3-4s per file write cycle on slow disks,
and it does a thousand write cycles. The problem is taht reflink is
so much faster than the write cycle that it's doing many more
snapshots on slow disks than fast disks, and this slows it down even
more.
e.g. the pmem system that takes 18s to run does just under 1000
snapshots - roughly one per file write. 20 minutes into the iscsi
based test, it's only done ~300 write cycles but there are almost
10,000 snapshots been taken. IOWs, we're doing 30 snapshots a file
write, not ~1.
Fix this by rate limiting snapshots to at most 1 per whole file
write. This reduces the number of snapshots taken on fast devices by
~50% (runtime on pmem device went from 18s -> 8s) but reduced it to
1000 on slow devices and reduced runtime from 3671s to just 311s.

Test generic/422 hardcodes in the output file how much space files it
creates are supposed to take up on disk. This doesn't work when
additional space is allocated for extended attributes for ACLs or
SELinux labels.
Instead, record the actual space used in generic/422.full, and only
check if the writeback changes the space used.

In this commit a new test case is added to test that i_size races
don't occur under dio reads/writes. We add a program in /src dir,
which has a writer to issue some append dio writes. Meanwhile it
has a reader in this test to do some dio reads. As we expect,
reader should read nothing or data with 'a'. But it might read some
data with '0'.
The bug can be reproduced by this test case [1].

Run delalloc writes & append writes & non-data-integrity syncs
concurrently to test the race between block map change vs writeback.
This is to cover an XFS bug that data could be written to wrong
block and delay allocated blocks are leaked because the block map
was changed due to the removal of speculative allocated eofblocks
when writeback is in progress.
And this test partially mimics what lustre-racer[1] test does, using
which this bug was first found.

The config variable OVERLAY_MOUNT_OPTIONS is used to configure
the overlay mount options when running ./check -overlay.
The config variable MOUNT_OPTIONS is used to configure the
mount options for base fs.
If config sets value of OVERLAY_MOUNT_OPTIONS and
does not set MOUNT_OPTIONS, the value of MOUNT_OPTIONS
may be leftover from previous _overlay_config_override, so
don't use that value for base fs mount.

Move mount options from overlay_mount() into _overlay_mount_dirs()
