[PATCH] [GFS2] set plock owner in GETLK info

From: swhiteho
Date: Mon Jul 09 2007 - 12:35:37 EST


From: David Teigland <teigland@xxxxxxxxxx>

Set the owner field in the plock info sent to userspace for GETLK.
Without this, gfs_controld won't correctly see when the GETLK from a
process matches one of the process's existing locks.
