From 17294e69c4cd299da7ba3ca8077e24be76bd61b1 Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Thu, 26 Feb 2015 13:58:54 +0100 Subject: [PATCH] honor MEMF_no_refcount in alloc_heap_pages() Non-anonymous allocations with this flag set should - for the purpose of the availability check - be treated just like anonymous ones, as they wouldn't lead to a reduction of ->outstanding_pages.
