Further plans:

   1) We seriously want to tackle the elimination of the PREEMPT_RT
   annoyance #1, aka BKL. The Big Kernel Lock is still used in ~330
   files all across the kernel. A lot of work has been done already to
   push down the lock into the code which still thinks it needs to be
   protected by it. Some work has been done already in the (a little
   bit stale) kill-the-BKL and core/kill-the-BKL branches of the -tip
   git tree. If you want to help, please check those branches whether
   the code has been tackled already or not to avoid redundant
   work. If you decide to take care of one please note it on:

       http://rt.wiki.kernel.org/index.php/Big_Kernel_Lock

We (I) can't write to this file :)

However, I'll try to attack the remaining bkl that resides in tty...

I took a look at the perms, then the history - looks like you sorted it out.
