From be5b779ae9ce64ede0a8f4939360b0320bb257e2 Mon Sep 17 00:00:00 2001 From: Jiri Kosina Date: Mon, 15 Oct 2012 23:42:55 +0200 Subject: [PATCH] random: make it possible to enable debugging without rebuild 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.
