A bug in file cloning/reflinking was recently found that afftected both
Btrfs and XFS, which was caused by allowing the cloning of an eof block
into the middle of a file when the eof is not aligned to the filesystem's
block size.
The fix consists of returning the errno -EINVAL to user space when the
arguments passed to the system call lead to the scenario of data
corruption. However this overlaps with some cases where the system call,
in Btrfs, returned -EOPNOTSUPP, which means we are trying to reflink
inline extents. That is unsupported in Btrfs due to the huge complexity
of supporting it (due to copying and trimming inline extents, deal with
eventual compression, etc).
We have a few btrfs test cases that verify that attempts to clone inline
extents result in a failure, and are currently expecting an -EINVAL error
message from the output of the cloner program. So create a filter that
converts error messages related to the -EOPNOTSUPP error to messages
related to the -EINVAL error, so that the test can run both on patched
and non-patched linux kernels.
The corresponding btrfs patch for the linux kernel is titled:
"Btrfs: fix data corruption due to cloning of eof block"
And the VFS change that introduces the -EINVAL error return was introduced
by the following linux kernel commit (landed in 4.20-rc1):
07d19dc9fbe9 ("vfs: avoid problematic remapping requests into partial EOF block")
The btrfs patch is not yet in Linus' tree (it was submitted around the
same time as this change) and the VFS change was introduced in 4.10-rc1.

This bug is exposed by populating a high level qgroup, and then make
it childless with old qgroup numbers, and finally do rescan.
Normally rescan should zero out all qgroups' accounting number, but
due to a kernel bug which won't mark childless qgroups dirty, their
on-disk data is never updated, thus old numbers remain and cause
qgroup corruption.
Fixed by the following kernel patch:
"btrfs: qgroup: Dirty all qgroups before rescan"

The error message in newer btrfs utilities contains name of the
property, we want to filter it out so it matches golden output. There's
an optional parameter with property name that is matched against the
command output.

btrfs has started emitting new information from
cmd_subvol_delete(), so filter that out or it breaks btrfs/001:

One problem was the output of "uniq -c" which added spaces depending
on the size of the count value (e.g. one space less for 10+ devices).
The second problem was that "btrfs fi show" was doing the same:
"devid %4llu size %s used %s path %s".

Not sure how this happened, but filter.btrfs including
itself leads to immense sadness for any file that includes it.
(I got a segfault when I tried to run 307)
