Subject: [RFC v6 18/40] ext4: Add richacl support
Date: Tue, 4 Aug 2015 13:53:16 +0200 [thread overview]
Message-ID: <1438689218-6921-19-git-send-email-agruenba@redhat.com> (raw)
In-Reply-To: <1438689218-6921-1-git-send-email-agruenba@redhat.com>
From: "Aneesh Kumar K.V" <aneesh.kumar@linux.vnet.ibm.com>
Support the richacl permission model in ext4. The richacls are stored
in "system.richacl" xattrs. Richacls need to be enabled by tune2fs or
at file system create time.
