From 5043a9643fe65347badf33dca9e045d991e9c049 Mon Sep 17 00:00:00 2001 From: Wang Shilong <wshilong@ddn.com> Date: Thu, 13 Jun 2019 16:29:53 +0900 Subject: [PATCH] f2fs: only set project inherit bit for directory It doesn't make any sense to have project inherit bits for regular files, even though this won't cause any problem, but it is better fix this.
