[PATCHSET 0/5] fstests: random fixes for v2023.06.18

[Darrick J. Wong]

Hi all,

Here's the usual odd fixes for fstests.

If you're going to start using this mess, you probably ought to just
pull from my git trees, which are linked below.

This is an extraordinary way to destroy everything.  Enjoy!
Comments and questions are, as always, welcome.

[PATCH 1/5] xfs/529: fix bogus failure when realtime is configured

[Darrick J. Wong]

From: Darrick J. Wong <djwong@kernel.org>

If I have a realtime volume configured, this test will sometimes trip
over this:

XFS: Assertion failed: nmaps == 1, file: fs/xfs/xfs_dquot.c, line: 360
Call Trace:

The test injects the bmap_alloc_minlen_extent error, which refuses to
allocate file space unless it's exactly minlen long.  However, a
precondition of this injection point is that the free space on the data
device must be sufficiently fragmented that there are small free
extents.

However, if realtime and rtinherit are enabled, the punch-alternating
call will operate on a realtime file, which only serves to write 0x55
patterns into the realtime bitmap.  Hence the test preconditions are not
satisfied, so the test is not serving its purpose.

Fix it by disabling rtinherit=1 on the rootdir so that we actually
fragment the bnobt/cntbt as required.

[PATCH 2/5] xfs/569: skip post-test fsck run

[Darrick J. Wong]

From: Darrick J. Wong <djwong@kernel.org>

This test examines the behavior of mkfs.xfs with specific filesystem
configuration files by formatting the scratch device directly with those
exact parameters.  IOWs, it doesn't include external log devices or
realtime devices.  If external devices are set up, the post-test fsck
run fails because the filesystem doesnt' use the (allegedly) configured
external devices.  Fix that by adding _require_scratch_nocheck.

This case is a regression test case for:
  9c92ee2 ("xfs: validate sb_logsunit is a multiple of the fs blocksize")

So I think it's better to write this major commit at first, before recording the
secondary one.

What kind of error should be ignored at here?

Ok.  I guess that's a result of this test predating _fixed_by.

Also I'll update this with the real kernel commit id, now that there is
one.

The same new logsunit validation code, when ported to userspace, causes
xfs_db to emit verifier complaints that disturb the golden output.

Thanks, I'll replace "_fixed_by_git_commit kernel" with "_fixed_by_kernel_commit"
when I merge this patch. Others looks good to me.

[PATCH 4/5] xfs/041: force create files on the data device

From: Darrick J. Wong <djwong@kernel.org>

Since we're testing growfs of the data device, we should create the
files there, even if the mkfs configuration enables rtinherit on the
