From f78bac2c8e69144781e271d9771bae8dbb4e7098 Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Wed, 7 Mar 2018 17:10:03 -0800 Subject: block: Use the queue_flag_*() functions instead of open-coding these Except for changing the atomic queue flag manipulations that are protected by the queue lock into non-atomic manipulations, this patch does not change any functionality.
