Introduce helpers _fixed_by_{kernel,git}_commit() and
_fixed_in_{kernel_,}version() that can be used to hint testers why a
test might be failing and aid in auto-generating of expunge lists for
downstream kernel testing.
A test may be annotated with multiple hints, for example:
_fixed_by_kernel_commit 09889695864 xfs: foo
_fixed_by_kernel_commit 46464565465 ext4: bar
_fixed_in_version xfsprogs v5.15
Annotate fix kernel commits for some overlayfs tests.
Annotate fix kernel version for some overlayfs tests testing
for legacy behavior whose fixes are not likely to be backported
to stable kernels.
This is modeled after LTP's 'make filter-known-fails' and
print_failure_hints() using struct tst_tag annotations.
