From: Chandan Rajendra Date: Mon, 21 Dec 2015 07:01:46 +0000 (+1100) Subject: btrfs/096: work on non-4k block sized filesystems X-Git-Tag: v2022.05.01~2729 X-Git-Url: http://git.apps.os.sepia.ceph.com/?p=xfstests-dev.git;a=commitdiff_plain;h=d5cb320a2e23a1263910d8f52b2556ee4f5afe7c btrfs/096: work on non-4k block sized filesystems This commit makes use of the new _filter_xfs_io_blocks_modified filtering function to print information in terms of file blocks rather than file offset.
