Message-ID: <20160305003737.28738.35234.stgit@birch.djwong.org> Date: Fri, 04 Mar 2016 16:37:37 -0800 From: "Darrick J. Wong" <darrick.wong@...cle.com> To: david@...morbit.com, darrick.wong@...cle.com Cc: linux-ext4@...r.kernel.org, linux-btrfs@...r.kernel.org, fstests@...r.kernel.org, xfs@....sgi.com Subject: [PATCH 03/12] reflink: fix fragmentation tests to work on >4k block size filesystems 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.
