Subject: [RFC v3 23/45] ext4: Add richacl support
Date: Fri, 24 Apr 2015 13:04:20 +0200	[thread overview]
Message-ID: <423297a27857a1e1322ce7ec30485058f7ea9176.1429868795.git.agruenba@redhat.com> (raw)
In-Reply-To: <cover.1429868795.git.agruenba@redhat.com>
In-Reply-To: <cover.1429868795.git.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.
