From a717135c23fa60cfaf0c3768e8e72383237ce88d Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Fri, 13 Oct 2017 10:27:45 -0700 Subject: [PATCH] FROMLIST: f2fs: expose some sectors to user in inline data or dentry case (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.
