Currently, on 5.2.0-rc4+ kernel, when I run xfs/191 with upstream
xfsprogs, I get the following errors because mkfs.xfs binary has
changed a lot.

pass -d agsize=8192b /dev/sda11
pass -d agsize=65536s /dev/sda11
pass -d su=0,sw=64 /dev/sda11

fail -r size=65536,rtdev=$fsimg /dev/sda11
fail -r rtdev=$fsimg /dev/sda11
fail -i log=10 /dev/sda11
--------------------------

"pass -d su=0,sw=64 /dev/sda11", expect fail, this behavior has been
fixed by commit 16adcb88(mkfs: more sunit/swidth sanity checking).

"fail -n log=15 /dev/sda11" "fail -i log=10 /dev/sda11", expect pass,
this option has been removed since commit 2cf637c(mkfs: remove
logarithm based CLI option).

"fail -r size=65536,rtdev=$fsimg /dev/sda11" "fail -r rtdev=$fsimg
/dev/sda11" works well if we disable reflink, fail if we enable
reflink. It fails because reflink was not supported in realtime
devices since commit bfa66ec.

"b" or "s" suffix without specifying their size has been supported
since xfsprogs v4.15.0-rc1.

I change the expected result for compatibility with current xfsprogs
and add rtdev test with reflink.

I'd suggest to use a loop device to replace SCRATCH_DEV, to avoid some failures
caused by different stripe alignment of SCRATCH_DEV (refer to xfs/513).  Or we
need to think about the stripe alignment in this case.

I also met stripe size problem with log section in[1], but it failed on
mount step.  Can you give me a mkfs example and let me understand?


Sure.

Due to stripe alignment, the internal log size (8192) is too large.
Must fit within an allocation group.
Usage: mkfs.xfs

Thanks. I see. I will send a v4 patch to use loop dev. Thanks for your review.

All these failures gone after I turn to use /dev/loop0 to be SCRATCH_DEV.
