kbuild: kselftest error

[Drew Fustini]

Hi - I noticed the kselftest target in the kernel Makefile and decided
to try it out of curiosity:

afustini at lappy486:~/dev/linux/lappy486/git/kernels/mainline$ sudo make
kselftest

Has anyone run kselftest successfully?

I ran into an error that I'm trying to figure out:

== Testing sysctl behavior against /proc/sys/vm/swappiness ==
Writing test file ... ok

Writing sysctl from shell ... ok

I'm running kernel that I compiled from linus's tree 2 days ago.

After encountering the error, I turned on all the testing config options
I could find under the kernel hacking category.  However, I encountered
the same kselftest error with the newly built kernel:
