Subject: [PATCH -V7 06/26] vfs: Add IS_RICHACL() test for richacl support
Date: Tue, 18 Oct 2011 21:02:41 +0530 [thread overview]
Message-ID: <1318951981-5508-7-git-send-email-aneesh.kumar@linux.vnet.ibm.com> (raw)
In-Reply-To: <1318951981-5508-1-git-send-email-aneesh.kumar@linux.vnet.ibm.com>
From: Andreas Gruenbacher <agruen@kernel.org>
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.
Acked-by: David Howells <dhowells@redhat.com>
