This works for xfstests generic/319 on 32-bit x86. The xfstests run was okay, with a lockdep in the middle and a crash in xfs/300. Neither the lockdep nor the crash could reproduced by running individual tests one by one. generic/319 itself fails only because it couldn't find its _cleanup routine. I'm not sure if I'm using v1 or v2 of generic/319. The kernel is set to the commit just before the latest aio-next merge, which is causing severe problems here. xfsprogs was the latest production xfsprogs because my copy of xfstests is having trouble checking v4 XFS filesystems otherwise. Will test xfs_node_toosmall patch v2 once I get home. Thanks! Michael _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
