The first is a regression introduced by the discontiguous buffer support in the prefetch code, which Eric Sandeen found. I've written a slightly different fix for it than Eric did, but the concept for the fix is all Eric's work. The second patch is not actually a regression, but the filesystem that triggered the above regression can't actually be repaired in a sane amount of time because of an array insertion algorithm with exponential cost. It's trivial to fix, and it means xfs_repair can actually run to completion quickly rather than burn CPU for hours getting nothing done. These fixes mean I'll probably release a 3.2.0-rc3 once they've been reviewed and go into the tree.... Cheers, Dave. _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
