Due to the fact that btrfs uses different max extent size for
compressed and non-compressed write, it calculates metadata
reservation incorrectly.
This can leads to false ENOSPC alert for compressed write.
This test case will check it by using small fs and do parallel write
to trigger it.
It's highly recommened to use MOUNT_OPTIONS="-o compress" and
MKFS_OPTIONS="-n 64k" to trigger it. Without compression, it won't
be triggered.
The fix is not merged and may change in the future, but the function
is good enough:
btrfs: improve inode's outstanding_extents computation
btrfs: fix false enospc for compression

Define test groups for those tests which have _require_xfs_io_command
for punch, collapse, insert, and zero. This makes it easier to
exclude tests that use one of these fallocate commands. Or if you
want to specifically test for those fallocate commands you can do
this.
This obviates an out-of-tree xfstests patch I maintain which used an
XFS_IO_AVOID environment variable to suppress running tests that use
punch, collapse, insert, etc. This was rejected because of the
claim that it could be done using groups. So this commit is in
response to those upstream comments.

Update the following quick/auto tag based on their execution time
btrfs/007
btrfs/050
btrfs/100
btrfs/101
Two systems are used to determine their execution time. One is
backed by an SATA spinning rust, whose maximum R/W speed is about
100MB/s, modern desktop performance. (VM1)
Another one is a VM inside a openstack pool, with stronger CPU and
memory performance along with high latency storage. Maximum R/W
speed is around 150MB/s, latency is much higher than normal HDD
though. (VM2)
The 'quick' standard is a little more restrict, only when both
systems pass the test within 30s(+/- 10%), while 'auto' is less
restrict, any system can pass within 5min(+/- 10%) will still stay
in 'auto' group.
Other test cases don't fit both standards on both systems will not
be modified.
Execution time result: (Unit: seconds)

For fully deduped file, whose file extents are all pointing to the
same extent, btrfs backref walk can be very time consuming, long
enough to trigger softlock.
Unfortunately, btrfs send is one of the caller of such backref walk
under an O(n) loop, making the total time complexity to O(n^3) or
more.
And even worse, btrfs send will allocate memory in such loop, to
trigger OOM on system with small memory(<4G).
This test case will check if btrfs send will cause these problems.

Test that an invalid parent qgroup does not cause snapshot create to
force the FS readonly.
In btrfs, create_pending_snapshot() will go readonly on _any_ error return
from
btrfs_qgroup_inherit(). If qgroups are enabled, a user can crash their fs by
just making a snapshot and asking it to inherit from an invalid qgroup.
This patch does exactly that test. If the FS goes readonly that will be
reported and we will know that a regression was introduced.
