Subject: [PATCH 5.8 051/124] btrfs: move btrfs_rm_dev_replace_free_srcdev outside of all locks
Date: Mon, 12 Oct 2020 15:30:55 +0200 [thread overview]
Message-ID: <20201012133149.325509247@linuxfoundation.org> (raw)
In-Reply-To: <20201012133146.834528783@linuxfoundation.org>
From: Josef Bacik <josef@toxicpanda.com>
[ Upstream commit a466c85edc6fbe845facc8f57c408c544f42899e ]
When closing and freeing the source device we could end up doing our
final blkdev_put() on the bdev, which will grab the bd_mutex. As such
we want to be holding as few locks as possible, so move this call
outside of the dev_replace->lock_finishing_cancel_unmount lock. Since
we're modifying the fs_devices we need to make sure we're holding the
uuid_mutex here, so take that as well.
There's a report from syzbot probably hitting one of the cases where
the bd_mutex and device_list_mutex are taken in the wrong order, however
it's not with device replace, like this patch fixes. As there's no
reproducer available so far, we can't verify the fix.
