Hi Eric,
After merging the userns tree, today's linux-next build (powerpc
allyesconfig) failed like this:
arch/powerpc/kernel/mce.c: In function 'machine_process_ue_event':
arch/powerpc/kernel/mce.c:276:5: error: too many arguments to function 'memory_failure'
memory_failure(pfn, SIGBUS, 0);
^~~~~~~~~~~~~~
In file included from include/linux/pid_namespace.h:7:0,
from include/linux/ptrace.h:10,
from arch/powerpc/kernel/mce.c:27:
include/linux/mm.h:2571:12: note: declared here
extern int memory_failure(unsigned long pfn, int flags);
^~~~~~~~~~~~~~
Caused by commit
83b57531c58f ("mm/memory_failure: Remove unused trapno from memory_failure")
I have added the following patch for today:
From: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>
Date: Fri, 26 Jan 2018 11:54:39 +1100
Subject: [PATCH] mm/memory_failure: update powerpc for memory_failure() API change
