Subject: f2fs: expose some sectors to user in inline data or dentry case
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d628ac8abdfc0d3631cb76d6fc1f0b80d988b34f;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

f2fs: expose some sectors to user in inline data or dentry case

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.
