Maybe I just read it wrong.

I still have my results from testing 2.5.44-mm4, here's a cut and paste
from shmctl01:

I havn't seen this test fail before but I'll be happy to do more testing
with your patch to see if I can reproduce it.  You may also want to
consider updating LTP to the newest version.  I'm fairly certain that
shmctl01 hasn't been changed since the version you have, but just to be
consistent you may want to do that.

Thanks,
