Add process name and pid to locks warning 



It's fairly useless to complain about using an obsolete feature without
telling the user which process used it. My Fedora desktop randomly drops
this message, but I would really need this patch to figure out what
triggers is.

[ jlayton: print pid as well as process name ]
