Hi,
Thanks for merging the patch.
BTW. Do you have comments about:

http://thread.gmane.org/gmane.linux.kernel.lsm/19650

Here I posted all of the acceptable patches rebased on smack-next.
Moreover, I added measurements of impact of patches on both time and
memory consumption.
There were no comments about this patchset. Maybe something was lost?

Regards,
Tomasz Stanislawski
