Subject: [3.19-final|next-20150204] LTP OOM testsuite causes call-traces
Hi,
I first noticed call-traces in next-20150204 and tested on v3.19-final
out of curiosity.
So, oom3 | oom4 | oom5 from LTP tests produces call-traces in my logs
in both releases.
Yesterday, I sent a tarball to linux-mm/Shutemov which has material
for next-20150204.
The for-lkml tarball has stuff for v3.19-final.
As an example (please see dmesg files in attached tarball(s)):

LTP here is version 20150119.
I have created a 'mm-oom' testcase (for-lkml tarball) to be placed
into /path/to/ltp/runtest directory.
Then simply run:
root# ./runltp -f mm-oom
Please have a look at this.
If you need additional information, please let me know.
Thanks.
