From fade21f9f82ea6e0b42364a6e3d49f0450722afb Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Mon, 14 Nov 2011 23:06:09 +0100 Subject: [232/256] dm: Make rt aware Use the BUG_ON_NORT variant for the irq_disabled() checks. RT has interrupts legitimately enabled here as we cant deadlock against the irq thread due to the "sleeping spinlocks" conversion. Reported-by: Luis Claudio R.
