Subject: [PATCH v2 0/2] btrfs: fix a deadlock between chunk allocation and chunk tree modifications
Date: Fri, 8 Oct 2021 16:10:33 +0100 [thread overview]
Message-ID: <cover.1633705660.git.fdmanana@suse.com> (raw)
In-Reply-To: <cover.1633604360.git.fdmanana@suse.com>
From: Filipe Manana <fdmanana@suse.com>
This fixes a deadlock between a task allocating a metadata or data chunk
and a task that is modifying the chunk btree and it's not in a chunk
allocation or removal context. The first patch is the fix, the second one
just updates a couple comments and it's independent of the fix.
v2: Updated stale comment after the fix.

btrfs: fix deadlock between chunk allocation and chunk btree modifications
btrfs: update comments for chunk allocation -ENOSPC cases
