From c7e12b838989b0e432c7a1cdf1e6c6fd936007f6 Mon Sep 17 00:00:00 2001 From: Pavel Emelianov Date: Thu, 2 Nov 2006 22:07:03 -0800 Subject: [PATCH] Fix ipc entries removal Fix two issuses related to ipc_ids->entries freeing. 1. When freeing ipc namespace we need to free entries allocated with ipc_init_ids(). 2. When removing old entries in grow_ary() ipc_rcu_putref() may be called on entries set to &ids->nullentry earlier in ipc_init_ids(). This is almost impossible without namespaces, but with them this situation becomes possible. Found during OpenVZ testing after obvious leaks in beancounters.
