Subject: [PATCH -V2 03/16] vfs: Add IS_RICHACL() test for richacl support
Date: Sat, 3 Jul 2010 00:13:34 +0530 [thread overview]
Message-ID: <1278096227-16784-4-git-send-email-aneesh.kumar@linux.vnet.ibm.com> (raw)
In-Reply-To: <1278096227-16784-1-git-send-email-aneesh.kumar@linux.vnet.ibm.com>
From: Andreas Gruenbacher <agruen@suse.de>
Introduce a new MS_RICHACL super-block flag and a new IS_RICHACL() test
which file systems like nfs can use. IS_ACL() is true if IS_POSIXACL()
or IS_RICHACL() is true.
