Subject[PATCH 4.14 066/193] f2fs: expose some sectors to user in inline data or dentry case
Date
4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jaegeuk Kim <jaegeuk@kernel.org>

commit 5b4267d195dd887c4412e34b5a7365baa741b679 upstream.

If there's some data written through inline data or dentry, we need to shouw
st_blocks. This fixes reporting zero blocks even though there is small written
data.
