[PATCH mm-unstable v1 0/4] selftests/vm: fix some tests on 32bit

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I finally had the time to run some of the selftests written by me
(especially "cow") on x86 PAE. I found some unexpected "surprises" :)

With these changes, and with [1] on top of mm-unstable, the "cow" tests and
the "ksm_functional_tests" compile and pass as expected (expected failures
with hugetlb in the "cow" tests). "madv_populate" has one expected test
failure -- x86 does not support softdirty tracking.

#1-#3 fix commits with stable commit ids. #4 fixes a test that is not in
mm-stable yet.

A note that there are many other compile errors/warnings when compiling
on 32bit and with older Linux headers ... something for another day.
