Subject: [PATCH 5.4 02/22] btrfs: dont pass system_chunk into can_overcommit
Date: Fri, 16 Oct 2020 11:07:30 +0200	[thread overview]
Message-ID: <20201016090437.429937666@linuxfoundation.org> (raw)
In-Reply-To: <20201016090437.308349327@linuxfoundation.org>

From: Josef Bacik <josef@toxicpanda.com>

commit 9f246926b4d5db4c5e8c78e4897757de26c95be6 upstream

We have the space_info, we can just check its flags to see if it's the
system chunk space info.
