From 4ecd4fef3a074c8bb43c391a57742c422469ebbd Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 7 May 2015 09:38:13 +0200 Subject: block: use an atomic_t for mq_freeze_depth lockdep gets unhappy about the not disabling irqs when using the queue_lock around it. Instead of trying to fix that up just switch to an atomic_t and get rid of the lock.
