Subject: [PATCH 0/2] selftests/mlock2: Build warning fixes on Debian/m68k 4.0
Date: Mon,  9 Nov 2015 11:14:27 +0100	[thread overview]
Message-ID: <1447064069-21469-1-git-send-email-geert@linux-m68k.org> (raw)

	Hi,

The following 2 patches are needed to fix build warnings on Debian/m68k
4.0.

However, after wiring up the mlock2 syscall, the test fails with:

# ./mlock2-tests
fread kpageflags: Success
# 

as the fread() call returns 0, not 1.

The original commit description for the test said "Note that the limit
test needs to be run a normal user.". But running it as a non-root user
also fails:

$ ./mlock2-tests 
fopen kpageflags: Permission denied
$ ls -l /proc/kpageflags 
-r-------- 1 root root 0 Nov  9 11:05 /proc/kpageflags
$

What am I missing?

Thanks!

  selftests/mlock2: Add missing #define _GNU_SOURCE
  selftests/mlock2: Add ULL prefix to 64-bit constants
