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:
