Hi all,
Here is the new patch porting the first set of CrashMonkey tests to
xfstests. This patch batches 37 CrashMonkey tests, and tests them on a
file system of size 200MB. Each sub test is also followed by fsck to
check for metadata inconsistencies. This test is added to a new group
- regress.
Let me know if this looks good to you.
Thanks,
Jayashree
