Message-Id: <1447469663-3631-1-git-send-email-baiyaowei@cmss.chinamobile.com> Date: Sat, 14 Nov 2015 10:54:22 +0800 From: Yaowei Bai <baiyaowei@...s.chinamobile.com> To: viro@...iv.linux.org.uk, akpm@...ux-foundation.org, mikulas@...bright.com, ooo@...ctrozaur.com Cc: linux-fsdevel@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH 1/2] fs/stat.c: drop the last new_valid_dev check New_valid_dev() always returns true, so that's unnecessary to perform new_valid_dev() checks in some filesystems. Most checks of new_valid_dev() have been removed so let's drop this last one and then we can remove new_valid_dev() from the source code. No functional change.
