Message-ID: <20120419140719.17272.39008.stgit@warthog.procyon.org.uk> Date: Thu, 19 Apr 2012 15:07:19 +0100 From: David Howells <dhowells@...hat.com> To: linux-fsdevel@...r.kernel.org Cc: dhowells@...hat.com, linux-nfs@...r.kernel.org, linux-cifs@...r.kernel.org, samba-technical@...ts.samba.org, linux-ext4@...r.kernel.org, wine-devel@...ehq.org, kfm-devel@....org, nautilus-list@...me.org, linux-api@...r.kernel.org, libc-alpha@...rceware.org Subject: [PATCH 6/6] xstat: eCryptFS: Return extended attributes Return extended attributes from the eCryptFS filesystem, dredged up from the lower filesystem. XSTAT_INFO_ENCRYPTED is set on the files whose cryptography is handled by eCryptFS. Possibly eCryptFS should also set FS_COMPR_FL on its compressed files.
