xfstests 241: run parallel dbench
PATCH 1/1 xfstests 241: run parallel dbench
ext4 was corrupting inode table bitmaps due to a mishmash of atomic & nonatomic bitops. This got broken twice and fixed twice; let's add a test.
On a 4-way box this reliably ends up with a corrupted filesystem if we get it wrong (upstream as of 2.6.35 at least is fine again)

Looks good, except it's missing a 241.out file for the golden output.
Cheers,
Dave.
