-Subject: [PATCH 4/6] LU-2096 lprocfs: symlinks for forward compatibility
-
-Currently, the "ofd" device is still named "obdfilter" in the Lustre
-configuration and in /proc/fs/lustre.  It would be better to name it
-"ost" which is has been the long term goal but retain the "ofd"
-module name.
-
-The per-OST device statistics should really be under "ost/{target}",
-like the per-MDT statistics are under "mdt/{target}" already in 2.x.
-
-Similarly, the "OSS" statistics have always been under "ost/OSS", but
-would be better in their own "oss" subdirectory much like what is done
-for "MDS" statistics.
-
-Add symlinks in lprocfs for "ost/OSS -> oss", "obdfilter -> ofd -> ost",
-and "obdfilter/{target} -> ost/{target}" for forward compatibility so
-that when we finally are able to make these changes to the module names
-userspace tools and scripts can have a smoother transition between
-Lustre versions.
