f2fs: skip unnecessary node writes during fsync
If multiple redundant fsync calls are triggered, we don't need to write its node pages with fsync mark continuously. So, this patch adds FI_NEED_FSYNC to track whether the latest node block is written with the fsync mark or not. If the mark was set, a new fsync doesn't need to write a node block. Otherwise, we should do a new node block with the mark for roll-forward recovery. Signed-off-by: Jaegeuk Kim <jaegeuk.kim@samsung.com>
