Subject: [PATCH] f2fs: avoid duplicated permission check for "trusted." xattrs
Date: Thu, 19 Jul 2018 09:23:57 +0900 [thread overview]
Message-ID: <20180719002357.9882-1-hyc.lee@gmail.com> (raw)
From: Hyunchul Lee <cheol.lee@lge.com>
Because xattr_permission already checks CAP_SYS_ADMIN
capability, we don't need to check it.
