Proposed patch at: http://review.whamcloud.com/#/c/11014/

[James Nunez (Inactive)]

The patch http://review.whamcloud.com/#/c/11014/ added a version string to mount.lustre, mkfs.lustre, lfs.c, and lctl.c.

Should a version string be added to other Lustre utilities? Candidate configuration utilities, from the Lustre manual, are:
l_getidentity, ll_decode_filter_fid, ll_recover_lost_found_objs, llobdstat, llog_reader, llstat, llverdev, lshowmount, lst, lustre_rmmod, lustre_rsync, plot-llstat, routerstat, and tunefs.lustre
