Subject: Does anyone use CONFIG_TINY_PREEMPT_RCU?

Hello!

I know of people using TINY_RCU, TREE_RCU, and TREE_PREEMPT_RCU, but I
have not heard of anyone using TINY_PREEMPT_RCU for whom TREE_PREEMPT_RCU
was not a viable option (in contrast, the people running Linux on
tiny-memmory systems typically use TINY_RCU).  Of course, if no one
really needs it, the proper thing to do is to remove it.

So, if you need TINY_PREEMPT_RCU, please let me know.  Otherwise, I will
remove it, probably in the 3.9 timeframe.

							Thanx, Paul
