Hi folks, This is version 2 of the DIO vs delalloc patchset I posted here: http://oss.sgi.com/archives/xfs/2014-03/msg00313.html The changes to this version are: - the bug fix to patch 2 that Brain noticed, - I dropped the delalloc extent splittting patch because with the fix to patch 2 I can't trigger that bug anymore, and that patch was causing transaction overruns in xfs/297. Hence without an existing reproducer, I won't try to fix that problem. - the last patch is new, and is a bug in the collapse range code where it fails to shift the last N extents correctly if there are N delalloc extents before the shifted range. With these 6 patches, all of the xfstests fsx/fsstress tests pass on 1k, 2k and 4k block size filesystems, with and without CRCs enabled, on 1, 2 and 16p test VMs. I'm much happier with these patches now - I don't think that there are more problems lurking, but only time will tell. I'd like to get these fixes to Linus for 3.15 (probably for -rc2), so eyeballs and testing would be appreciated. Cheers, Dave. _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
