I did try to make it work with variable sized block sizes, But I got stuck working with md5sum (since we would need two sets of md5sums, due to _test_generic_punch() being invoked with and without '-k' option per block size). Since 4k block size support for Btrfs on ppc64 is already being worked on, I think its better to prevent execution of generic/255 for block sizes greater than 4k. Apologies for not including the above description in the patch. - chandan _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
