I am happy to say, that I've managed to get rmap12e working correctly with XFS-CVS head. Some minor modifications to mm/vmscan.c and fs/buffer.c but, I've not seen corruption yet. 504 root 15 0 1024 1000 360 R 94.0 1.6 756:00 blowup-xfs (fsx-linux.c) I will be trying some of the test XFS programs in the tree as well today. Shawn.
