Subject: [PATCH 08/13] btrfs: adjust the arguments for btrfs_should_throttle_delayed_refs
Date: Fri, 13 Mar 2020 17:23:25 -0400 [thread overview]
Message-ID: <20200313212330.149024-9-josef@toxicpanda.com> (raw)
In-Reply-To: <20200313212330.149024-1-josef@toxicpanda.com>
We want to be able to call this without a trans handle being open, so
adjust the arguments to be the fs_info and the delayed_ref_root instead
of the trans handle.
