f2fs: reduce competition among node page writes We do not need to block on ->node_write among different node page writers e.g. fsync/flush, unless we have a node page writer from write_checkpoint. So it's better use rw_semaphore instead of mutex type for ->node_write to promote performance. Signed-off-by: Chao Yu <chao2.yu@samsung.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
