Subject: [PATCH] proc: more debugging for "already registered" case
Date: Sat, 6 Sep 2008 01:36:46 +0400 [thread overview]
Message-ID: <20080905213646.GF11569@x200.localdomain> (raw)
Print parent directory name as well.
Target is to catch non-creation of parent directory when proc_mkdir will
return NULL and all subsequent registrations go directly in /proc
instead of intended directory.
