Regression test for a btrfs issue where if right after the snapshot
creation ioctl started, a file write followed by a file truncate
happened, with both operations increasing the file's size, the created
snapshot would capture an inconsistent state of the file system tree.
That state reflected the file truncation but it didn't reflect the
write operation, and left a gap between two file extent items (and
that gap corresponded to the total or a partial area of the write
operation's range).
This issue was fixed by the following linux kernel patch:

Fix two problems in generic/299
1. Remove $seqres.full before test, otherwise the file is growing all
the time.
2. Make sure fio really exits, otherwise fio would block umount. $pid is
the pid of function run_check not fio, sometimes fio is still there when
$pid is dead and blocking umount.

Stress btrfs' block group allocation and deallocation while running
fstrim in parallel. Part of the goal is also to get data block groups
deallocated so that new metadata block groups, using the same physical
device space ranges, get allocated while fstrim is running. This caused
several issues ranging from invalid memory accesses, kernel crashes,
metadata or data corruption, free space cache inconsistencies, free
space leaks and memory leaks.

generic/315 fails messily if the fallocate command isn't present.
generic/299 also uses "fallocate" and "truncate" binaries which may
not be present.
Switch both to use xfs_io, and we already have the _require for
that, because it's what every other test uses...

This test verifies that replacing a xattr's value is an atomic
operation. This is motivated by an issue in btrfs where replacing
a xattr's value wasn't an atomic operation, it consisted of
removing the old value and then inserting the new value in a
btree. This made readers (getxattr and listxattrs) not getting
neither the old nor the new value during a short time window.

This test creates a large-ish directory structure using
fsstress, and does a dump/restore to make sure we dump
all the files.
Without the fix for the regression caused by:
c7cb51d xfs: fix error handling at xfs_inumbers
we will see failures like:
-xfsrestore: 486 directories and 1590 entries processed
+xfsrestore: 30 directories and 227 entries processed
as it fails to process all inodes.
I think that existing tests have a much smaller set of files,
and so don't trip the bug.
I don't do a file-by-file comparison here, because for some
reason the diff output gets garbled; this test only checks
that we've dumped & restored the correct number of files.
