From f705ab956b3a0377181c9d73b235ad5bf4020937 Mon Sep 17 00:00:00 2001 From: Paul Gortmaker Date: Wed, 11 Jul 2012 17:35:01 -0400 Subject: [PATCH] tipc: limit error messages relating to memory leak to one line With the default name table size of 1024, it is possible that the sanity check in tipc_nametbl_stop could spam out 1024 essentially identical error messages if memory was corrupted or similar. Limit it to issuing no more than a single message. The actual chain number (i.e. 0 --> 1023) wouldn't provide any useful insight if/when such an instance happened, so don't bother printing out that value.
