Subject: [PATCH 2/2] bdi: Use might_alloc()
Date: Wed, 13 Jan 2021 14:40:33 +0100 [thread overview]
Message-ID: <20210113134033.3569683-2-daniel.vetter@ffwll.ch> (raw)
In-Reply-To: <20210113134033.3569683-1-daniel.vetter@ffwll.ch>
Now that my little helper has landed, use it more. On top of the
existing check this also uses lockdep through the fs_reclaim
annotations.
