For the uninitiated :)  This applies on top of:

http://git.kernel.org/?p=fs/xfs/xfstests-dev.git

Apply my patch & build it with make... you'll need xfsprogs,
xfsprogs-devel, and xfsprogs-qa-devel (or make install-dev, make
install-qa from the xfsprogs tarball)*  A few other standard devel
packages like e2fsprogs-devel, acl-devel, attr-devel, libaio-devel are
needed too.

edit a local.config file in the top level dir:

TEST_DEV=/dev/sdb1       # device containing TEST PARTITION
TEST_DIR=/mnt/test       # mount point of TEST PARTITION
SCRATCH_DEV=/dev/sdb3    # device containing SCRATCH PARTITION
SCRATCH_MNT=/mnt/scratch # mount point for SCRATCH PARTITION

mkfs.ext4 the $TEST_DEV

./check -ext4 -g generic

-Eric

*another TODO is probably to make ./configure cope with lack of at least
the xfsprogs-qa-devel headers.  There's still some work to make this
cleaner/easier but this at least gets things going.
