ocfs2: fix write() performance regression
ocfs2: fix write() performance regression patch 4e9563fd55ff4479f2b118d0757d121dd0cfc39c in mainline. On file systems which don't support sparse files, Ocfs2_map_page_blocks() was reading blocks on appending writes. This caused write performance to suffer dramatically. Fix this by detecting an appending write on a nonsparse fs and skipping the read. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
