Usually xfs/186 _notrun on crc enabled XFS because of _require_attr_v1, since v2 attr format is always enabled on v5 XFS. But when testing on 512B block size XFS, i.e. MKFS_OPTIONS="-m crc=0 -b size=512", test fails. This is because crc enabled XFS was created in the end, not 512B block size XFS with crc disabled, and that's not what we want to test. The reason why _scratch_mkfs_xfs creates a different XFS than expected is that, it may ignore $MKFS_OPTIONS if mkfs fails due to conflicts between $MKFS_OPTIONS and the provided mkfs options. In the case of xfs/186, "-b size=512" conflicts with "-i size=512", and the first mkfs fails, then it ends up with a 4k block size XFS with crc enabled (the default config). Fix it by checking crc enablement status and attr version in the test, to make sure it's testing on expected XFS.

|
|
# Test bug in going from attr2 back to attr1 where xfs
|
|
# (due to xfs_attr_shortform_bytesfit)
|
|
# would reset the di_forkoff to the m_offset instead of
|
|
# leaving the di_forkoff alone as was intended.
|
|
#
|
|
# We create enough dirents to push us past m_attroffset,
|
|
# and create an EA so we have a fork offset
|
|
# and then turn on attr1 and add one more EA which
|
|
# will write over the shortform dirents.
