If we want to have bigalloc specific tests we should probably add a
helpers to check for bigalloc support in both kernel, and e2fsprogs
so this test does not fail on older kernel/older e2fsprogs.

Thanks!

Even though we do not need the distinction here I can see that it
might be useful when testing mkfs alone, also I can see that xfs is
doing the same thing so I guess we can be consistent.

_scratch_mkfs_ext4 might fail due to incompatible mkfs
options being passed in with MKFS_OPTIONS. This can be resolved by
ignoring MKFS_OPTIONS if it fails the first time in
_scratch_mkfs_ext4() see _scratch_mkfs_xfs().

Also I feel that the same should be done with _scratch_mount because
again we can have incompatible mount options in MOUNT_OPTIONS, or
SCRATCH_OPTIONS. But that's a different issue entirely.

Thanks!
-Lukas

Here you should really be using

_scratch_mkfs_ext4

Subject: [PATCH v3] xfstests/ext4: regression test for wrong assert in ext4_mb_normalize_request()

Regression test for:
b5b6077 ext4: fix wrong assert in ext4_mb_normalize_request()

Meanwhile make minor changes to _scratch_mkfs_ext4() in common/rc, _scratch_mkfs_ext4()
might fail due to conflicts between being passed options and MKFS_OPTIONS. We fix this
by ignoring MKFS_OPTIONS if it fails the first time(see _scratch_mkfs_xfs()), as suggested
by Lukas Czerner.
