From 852ec80983d682dc08a0573d37eeaa9814c4f6b1 Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Wed, 21 Jun 2017 10:55:47 -0700 Subject: blk-mq: Make it safe to quiesce and unquiesce from an interrupt handler Since blk_mq_quiesce_queue_nowait() can be called from interrupt context, make this safe. Since this function is not in the hot path, uninline it.
