Subject: [PATCH][IPX] Use existing sock refcnt debugging infrastructure
Date: Fri, 09 Nov 2007 16:42:05 +0300 [thread overview]
Message-ID: <473463AD.9000807@openvz.org> (raw)
Just like in the af_packet.c, the ipx_sock_nr variable is used
for debugging purposes.
Switch to using existing infrastructure. Thanks to Arnaldo for
pointing this out.
