Subject: [PATCH AUTOSEL 4.19 079/167] btrfs: scrub: fix circular locking dependency warning
Date: Tue, 3 Sep 2019 12:23:51 -0400 [thread overview]
Message-ID: <20190903162519.7136-79-sashal@kernel.org> (raw)
In-Reply-To: <20190903162519.7136-1-sashal@kernel.org>
From: Anand Jain <anand.jain@oracle.com>
[ Upstream commit 1cec3f27168d7835ff3d23ab371cd548440131bb ]
This fixes a longstanding lockdep warning triggered by
fstests/btrfs/011.
Circular locking dependency check reports warning[1], that's because the
btrfs_scrub_dev() calls the stack #0 below with, the fs_info::scrub_lock
held. The test case leading to this warning:
$ mkfs.btrfs -f /dev/sdb
$ mount /dev/sdb /btrfs
$ btrfs scrub start -B /btrfs
In fact we have fs_info::scrub_workers_refcnt to track if the init and destroy
of the scrub workers are needed. So once we have incremented and decremented
the fs_info::scrub_workers_refcnt value in the thread, its ok to drop the
scrub_lock, and then actually do the btrfs_destroy_workqueue() part. So this
patch drops the scrub_lock before calling btrfs_destroy_workqueue().
