Wong I applied your patch "[PATCH] xfs_db: bit fuzzing should read the right bit when flipping" on top of xfsprogs for-next branch (which contains commit ef209a960d82 "xfs_db: make write/fuzz -c and -d work on non-crc filesystems") and tested this patch. All worked fine on CRC enabled XFS, but test failed with non-CRC xfs as it missed lines like: Allowing fuzz of corrupted data with good CRC I did the following modifications and test passed with both CRC and non-CRC XFS, if you think it's OK then I can fold the changes to your patch and no need for a resend :) Thanks, Eryu Reviewed-by: Darrick J.
