Subject: [PATCH v2] f2fs: only set project inherit bit for directory
Date: Thu, 13 Jun 2019 16:29:53 +0900	[thread overview]
Message-ID: <1560410993-26330-1-git-send-email-wshilong1991@gmail.com> (raw)

From: Wang Shilong <wshilong@ddn.com>

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.
