[LAU] CONFIG_PREEMPT_RCU

[Brent Busby]

Looking over Linux kernel list archives and other places, it looks like 
when the "RCU Implementation" choice hit the mainline non-patched 
kernel, the option to choose "Preemptable RCU" caused quite a stir as 
many latent bugs were uncovered.

It looks like many bugs got fixed, but is it safe now?  Should one 
enable CONFIG_PREEMPT_RCU on a 2.6.29.6 kernel these days?  It seems to 
be available even without RT patches.
