    [PATCH] Fix ipc entries removal · c7e12b83
    Pavel Emelianov authored
    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
       This is almost impossible without namespaces, but with
       them this situation becomes possible.
    Found during OpenVZ testing after obvious leaks in beancounters.
