[PATCH] xfs/187: fix new sb_features2 ftype stop case running

[PATCH] xfs/187: fix new sb_features2 ftype stop case running

[Zorro Lang]

This case is too old, at that time there's no "ftype" feature for
XFS. Due to this case need to clear features2 bits when mkfs.xfs,
so ftype bit stop case running for long time.

We care 6 features2 bits in this case:

  "ATTR2, LAZYSBCOUNT, PROJID32BIT, CRC, FTYPE, FINOBT"

ATTR2 and LAZYSBCOUNT bits will be tested in case. FINBOT will be
disabled if CRC=0. So this patch only check and disable PROJID32BIT,
CRC and FTYPE features when mkfs.xfs.

Hi,

I think we shouldn't skip this case if user doesn't specify suitable
MKFS_OPTIONS and MOUNT_OPTIONS. Because this case need complex options,
nearly no one will specify these all options for xfstests at same time.

Thanks,
Zorro

We're doing stuff like this in way too many places to keep old tests
working with new xfsprogs as the defaults change and new options are
added. This is not maintainable in the long run.

I think we need to start marking test as requiring "old" filesystem
formats, and we configure the mkfs options required to create such a
filesystem in one place.

i.e. add a rule:

_require_old_xfs_format()
{
	# calculate necessary additional options to ensure
	# 16 bit project id, no CRCs, and no ftype.
	BASIC_MKFS_OPTIONS=.....

	# add "old" option to default mkfs option set
	export MKFS_OPTION=S"$MKFS_OPTIONS $BASIC_MKFS_OPTIONS"
}

And now any specific test that relies on a format not having CRCs,
ftype, etc, can simply _require_old_xfs_format(), and so we can
get rid of all the per-test magic we have to futz mkfs options into
the "old" format the test requires.

Cheers,

Dave.
