Subject: [PATCH v2 2/3] btrfs: disk-io: Remove unnecessary check before freeing chunk root
Date: Tue, 8 Oct 2019 12:49:08 +0800 [thread overview]
Message-ID: <20191008044909.157750-3-wqu@suse.com> (raw)
In-Reply-To: <20191008044909.157750-1-wqu@suse.com>
In free_root_pointers(), free_root_extent_buffers() has checked if the
@root parameter is NULL.
So there is no need checking chunk_root before freeing it.
