| |
2.6.36-stable review patch. If anyone has any objections, please let us know.
------------------
From: Eric Dumazet <eric.dumazet@gmail.com>
commit 6b1686a71e3158d3c5f125260effce171cc7852b upstream.
commit ea781f197d6a8 (use SLAB_DESTROY_BY_RCU and get rid of call_rcu()) did a mistake in __vmalloc() call in nf_ct_alloc_hashtable().
I forgot to add __GFP_HIGHMEM, so pages were taken from LOWMEM only.
