This is something the kernel VFS maintainer would rather see handled differently. This ticket tracks the changes upstream for the client as well as implement the needed server side changes.</p> LU-12514

If the patch is simple, maybe it could be backported to 2.12 as well.</p> <p>Another possibility is "lustre_osd" instead of "lustre_tgt".</p> <p>Agree. I only pushed the 'simple' patches so far. The other work is much more involved and I expect that is for 2.14</p> <p>I'm not suggesting to actually separate the client and server mount code for 2.13, just register a second <tt>filesystem_type</tt> with the existing code, just for forward compatibility for the new mount type. </p> <p>Oleg Drokin (green@whamcloud.com) merged in patch <a
