For tests that only overwrite part of a file, only consider the number of extents in the *rewritten* blocks when deciding if the FS fragmentation performance is satisfactory. (Also slip in a fix for xfs/127 so that it formats correctly when we specify big blocksizes via MKFS_OPTIONS.) Signed-off-by: Darrick J.
