Subject: [PATCH 5.4 017/152] btrfs: move the chunk_mutex in btrfs_read_chunk_tree
Date: Thu, 20 Aug 2020 11:19:44 +0200
Message-ID: <20200820091554.527061070@linuxfoundation.org> (raw)

commit 01d01caf19ff7c537527d352d169c4368375c0a1 upstream.

We are currently getting this lockdep splat in btrfs/161:

This is because btrfs_read_chunk_tree() can come upon DEV_EXTENT's and
then read the device, which takes the device_list_mutex.  The
device_list_mutex needs to be taken before the chunk_mutex, so this is a
problem.  We only really need the chunk mutex around adding the chunk,
so move the mutex around read_one_chunk.

An argument could be made that we don't even need the chunk_mutex here
as it's during mount, and we are protected by various other locks.
However we already have special rules for ->device_list_mutex, and I'd
rather not have another special case for ->chunk_mutex.
