[PATCH] SELinux: change isec semaphore to a mutex
This patch converts the remaining isec->sem into a mutex. Very similar locking is provided as before only in the faster smaller mutex rather than a semaphore. An out_unlock path is introduced rather than the conditional unlocking found in the original code.
