[PATCH 0/2] fstests: simplify per-fs _fixed_by_kernel_commit

[PATCH 0/2] fstests: simplify per-fs _fixed_by_kernel_commit

[Johannes Thumshirn]

Hi Zorro,

Christoph asked in https://lore.kernel.org/r/20260210155123.GA3552@lst.de
to introduce a _fixed_by_fs_commit helper, that encapulates the
 if [ $FSTYP" = fs ] && _fixed_by_kernel_commit XXXXXX "blah"
pattern.

Here's my take on it. I also thought about adding more helpers like:
- _fixed_by_btrfs_commit
- _fixed_by_xfs_commit
- _fixed_by_ext4_commit
but not sure if this is going too far.

Johannes Thumshirn (2):
  fstests: add _fixed_by_fs_commit helper
  fstests: use _fixed_by_fs_commit where appropriate

Re: [PATCH 1/2] fstests: add _fixed_by_fs_commit helper

Minor nit, but this looks a bit odd to me.  I usually prefer the
full blown if:

	if [ "$fstyp" = "$FSTYP" ]; then
		_fixed_by_kernel_commit $*
	fi

but if you want to short cut it, just put it all on a single line:

	[ "$fstyp" = "$FSTYP" ] && _fixed_by_kernel_commit $*

Otherwise looks good:

Re: [PATCH 2/2] fstests: use _fixed_by_fs_commit where appropriate
