Subject: [PATCH v6 2/3] btrfs: remove unused device_list_mutex for seed fs_devices
Date: Tue, 21 Sep 2021 12:33:24 +0800 [thread overview]
Message-ID: <457af6350aa51333fc584210d8dc5ca7e679f3f9.1632179897.git.anand.jain@oracle.com> (raw)
In-Reply-To: <cover.1632179897.git.anand.jain@oracle.com>
The btrfs_fs_devices::seed_list is of type btrfs_fs_devices as well and,
it is a pointer to the seed btrfs_fs_device in a btrfs created from a
seed devices.
In this struct, when it points to seed, the device_list_mutex is not
used. So drop its initialize.
