btrfs: source common/module when requiring module reload

Tests 163, 219, 225 and 242 require the btrfs module to be reloaded
in the middle of the test. If btrfs is compiled builtin, these tests
should be skipped, since we cannot unload it.

Today, this is what happens:

    QA output created by 242
    +./common/btrfs: line 405: _require_loadable_fs_module: command not found

Sourcing common/module in these tests fixes the issue by skipping the
test:
    btrfs/242       [not run] btrfs: must be a module.
    Ran: btrfs/242

generic/371: disable speculative preallocation regressions on XFS

Once in a very long while, the fallocate calls in this test will fail
due to ENOSPC conditions.  While in theory this test is careful only to
allocate at most 160M of space from a 256M filesystem, there's a twist
on XFS: speculative preallocation.

The first loop in this test is an 80M appending write done in units of
4k.  Once the file size hits 64k, XFS will begin speculatively
preallocating blocks past the end of the file; as the file grows larger,
so will the speculative preallocation.

Since the pwrite/rm loop races with the fallocate/rm loop, it's possible
that the fallocate loop will free that file just before the buffered
write extends the speculative preallocation out to 160MB.  With fs and
log overhead, that doesn't leave enough free space to start the 80MB
fallocate request, which tries to avoid disappointing the caller by
freeing all speculative preallocations.  That fails if the pwriter
thread owns the IOLOCK on $testfile1, so fallocate returns ENOSPC and
the test fails.

The simple solution here is to disable speculative preallocation by
setting an extent size hint if the fs is XFS.

check: run _check_filesystems in an OOM-happy subshell

In turn, repair (which inherited oom_score_adj=-1000 from ./check)
consumed so much memory that the OOM killer ran around killing other

dmthin: erase the metadata device properly before starting

Every now and then I see the following failure when running generic/347:

  --- generic/347.out
  +++ generic/347.out.bad
  @@ -1,2 +1,2 @@
   QA output created by 347
  -=== completed

Accompanied by the following dmesg spew:

device-mapper: thin metadata: sb_check failed: blocknr 7016996765293437281: wanted 0
device-mapper: block manager: superblock validator check failed for block 0

device-mapper: table: 253:2: thin-pool: Error creating metadata object
device-mapper: ioctl: error adding target to table

7016996765293437281 is of course the magic number 0x6161616161616161,
which are stale ondisk contents left behind by previous tests that wrote
known tests patterns to files on the scratch device.  This is a bit
surprising, since _dmthin_init supposedly zeroes the first 4k of the
thin pool metadata device before initializing the pool.  Or does it?

dd if=/dev/zero of=$DMTHIN_META_DEV bs=4096 count=1 &>/dev/null

Herein lies the problem: the dd process writes zeroes into the page
cache and exits.  Normally the block layer will flush the page cache
after the last file descriptor is closed, but once in a while the
terminating dd process won't be the only process in the system with an
open file descriptor!

That process is of course udev.  The write() call from dd triggers a
kernel uevent, which starts udev.  If udev is running particularly
slowly, it'll still be running an instant later when dd terminates,
thereby preventing the page cache flush.  If udev is still running a
moment later when we call dmsetup to set up the thin pool, the pool
creation will issue a bio to read the ondisk superblock.  This read
isn't coherent with the page cache, so it sees old disk contents and the
test fails even though we supposedly formatted the metadata device.

Fix this by explicitly flushing the page cache after writing the zeroes.

xfs/117: fix fragility in this fuzz test

This fuzz test has some fragility problems -- it doesn't do anything to
guarantee that the inodes that it checks for EFSCORRUPTED are the same
ones that it fuzzed, and it doesn't explicitly try to avoid victimizing
inodes in the same chunk as the root directory.  As a result, this test
fails annoyingly frequently.

Fix both of these problems and get rid of the confusingly named TESTDIR
variable.

btrfs: test log replay after directory fsync and moving a child directory

Test a particular scenario where we fsync a directory, then move one of
its children directories into another directory and then finally sync the
log trees by fsyncing any other inode. We want to check that after a power
failure we are able to mount the filesystem and that the moved directory
exists only as a child of the directory we moved it into.

This currently fails on a 5.12 kernel (and 5.13-rc1) but is fixed by a
patch with the following subject:

  "btrfs: fix removed dentries still existing after log is synced"

The failure is due to ending up with a directory that has 2 hard links
(two parent directories) as soon as the log replay procedure finishes,
which causes the tree checker to detect the issue and cause the mount
operation to fail with -EIO.

btrfs/187: fix test failure when using bash 5.0+ with debug enabled

When running btrfs/187 with a bash 5.0+ build that has debug enabled, the

  Ran: btrfs/187
  Failures: btrfs/187
  Failed 1 of 1 tests

This is because the process running dedupe_files_loop() executes the 'wait'
command in the trap it has setup and very often it receives the SIGTERM
signal while it is running the 'wait' command in the while loop of that
function - so executing the trap makes bash run 'wait' while it is already
running 'wait', triggering the warning message from bash.

That warning message was added in bash 5.0 by commit 36f89ff1d8b761
("SIGINT trap handler SIGINT loop fix"):

  https://git.savannah.gnu.org/cgit/bash.git/commit/?id=36f89ff1d8b761c815d8993e9833e6357a57fc6b

So fix this by making the trap set a local variable named 'stop' to the
value 1 and have the loop exit when the local variable 'stop' is 1.

generic/631: Add a check for extended attributes

Test case 631 fails for filesystems like exfat or vfat or any other
which does not support extended attributes.

The main reason for failure is not being able to mount overlayfs
with filesystems that do not support extended attributes.
mount -t overlay overlay -o "$l,$u,$w,$i" $mergedir

Above command would return an error as -
/var/mnt/scratch/merged0: wrong fs type, bad option, bad superblock
on overlay, missing codepage or helper program, or other error.

dmesg log reports the following -
overlayfs: filesystem on '/var/mnt/scratch/upperdir1' not supported

As per the overlayfs documentation -
"A wide range of filesystems supported by Linux can be the lower
filesystem, but not all filesystems that are mountable by Linux
have the features needed for OverlayFS to work. The lower filesystem
does not need to be writable. The lower filesystem can even be another
overlayfs. The upper filesystem will normally be writable and if it
is it must support the creation of trusted.* and/or user.* extended
attributes, and must provide valid d_type in readdir responses,
so NFS is not suitable. A read-only overlay of two read-only
filesystems may use any filesystem type."

As per the above statements from the overlayfs documentation,
it is clear that filesystems that do not support extended
attributes or d_type would not work with overlayfs.
This is why we see the error in dmesg log for upperdir1
which had an exfat filesystem.

This test case already checks for d_type but does not check for
extended attributes, hence add a check for it which would avoid
running this tests for filesystems that are not supported.
