Xiao Guangrong 9817626e72 thp: remove some code depend on CONFIG_NUMA ... If NUMA is disabled, hpage is used as page pre-alloc, so there are two cases for hpage: - it is !NULL, means the page is not consumed otherwise, - the page has been consumed If NUMA is enabled, hpage is just used as alloc-fail indicator which is not a real page, NULL means not fail triggered. So, we can release the page only if !IS_ERR_OR_NULL Signed-off-by: Xiao Guangrong <xiaoguangrong@linux.vnet.ibm.com> Cc: Andrea Arcangeli <aarcange@redhat.com> Cc: Hugh Dickins <hughd@google.com> Cc: David Rientjes <rientjes@google.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>		2012-10-09 16:22:26 +09:00
