New xfstests generic/308 causes XFS hang (high CPU use), at least on 32-bit

Wed Apr 10 09:31:17 CDT 2013

On casual glance, it looks like a test meant to test the end of 32-bit
offsets, built to test a specific ext4 case, and it happened to strafe XFS
on 32-bit in the process.  It is unknown to me whether a script with 64-bit
version of the numbers would have a bad effect.
