Date: Sun, 23 Dec 2012 15:15:08 -0500 From: Sasha Levin <sasha.levin@...cle.com> To: rientjes@...gle.com, Andrew Morton <akpm@...ux-foundation.org>, Johannes Weiner <hannes@...xchg.org>, Michal Hocko <mhocko@...e.cz>, Gavin Shan <shangw@...ux.vnet.ibm.com>, Sasha Levin <sasha.levin@...cle.com>, linux-mm@...ck.org, linux-kernel@...r.kernel.org Subject: [PATCH 3/3] mm, sparse: don't check return value of alloc_bootmem calls There's no need to check the result of alloc_bootmem() functions since they'll panic if allocation fails.
