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

Jaegeuk Kim · pundiramit · commit a717135c23fa · 2017-10-15T23:56:11.000+05:30
(from https://patchwork.kernel.org/patch/10005409/) 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.
