Subject: [PATCH v2 0/2] ipc: allocations cleanup

Some ipc objects use the wrong allocation functions: small objects can use kmalloc(),
and vice versa, potentially large objects can use kmalloc().

I think it's better to handle these patches via cgroups@ to avoid merge conflicts
with "memcg: enable accounting of ipc resources" patch included to 
"memcg accounting from OpenVZ" patch set.

v2:
- improved patch description

Vasily Averin (2):
  ipc sem: use kvmalloc for sem_undo allocation
  ipc: use kmalloc for msg_queue and shmid_kernel
