This is a note to let you know that I have just added a patch titled kernel/smp.c:on_each_cpu_cond(): fix warning in fallback path to the linux-3.13.y-queue branch of the 3.13.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.13.y-queue This patch is scheduled to be released in version 3.13.11.7. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.13.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ------ From 8bdd79205c4c396928eb5d3b44df61592487c71b Mon Sep 17 00:00:00 2001 From: Sasha Levin <sasha.levin@oracle.com> Date: Wed, 6 Aug 2014 16:08:14 -0700 Subject: kernel/smp.c:on_each_cpu_cond(): fix warning in fallback path commit 618fde872163e782183ce574c77f1123e2be8887 upstream. The rarely-executed memry-allocation-failed callback path generates a WARN_ON_ONCE() when smp_call_function_single() succeeds. Presumably it's supposed to warn on failures.
