So, this patch changes btrfs to do with reiserfs, ext3 and xfs do, which is to do the log replay even when mounted readonly. On a readonly device if log replay is required, the mount is aborted. Getting all of this right had required fixing up some of the error handling in open_ctree. Signed-off-by: Chris Mason --- Reading git-diff-tree failed
