Applied to the random tree, thanks.

[RESEND] [PATCH 1/2] random: make it possible to enable debugging without rebuild

2012-10-15 Thread Jiri Kosina
The module parameter that turns debugging mode (which basically means 
printing a few extra lines during runtime) is in '#if 0' block. Forcing 
everyone who would like to see how entropy is behaving on his system to 
rebuild seems to be a little bit too harsh.

If we were concerned about speed, we could potentially turn 'debug' into a 
static key, but I don't think it's necessary.

Drop the '#if 0' block to allow using the 'debug' parameter without rebuilding.
