Subject: [PATCH] conntrack: allow nf_ct_alloc_hashtable() to get highmem pages
Date: Wed, 27 Oct 2010 11:09:15 +0200 [thread overview]
Message-ID: <1288170555.2709.63.camel@edumazet-laptop> (raw)
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.
