From 1c57ed19a228bf7012474b9008f61e606f30c26f Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Mon, 14 Nov 2011 23:06:09 +0100 Subject: [PATCH 272/365] 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.
