Subject: [PATCH 16/25] lightnvm: pblk: remove pblk_gc_stop
Date: Wed, 20 Dec 2017 18:21:56 +0100 [thread overview]
Message-ID: <20171220172205.26464-17-m@bjorling.me> (raw)
In-Reply-To: <20171220172205.26464-1-m@bjorling.me>
From: Hans Holmberg <hans.holmberg@cnexlabs.com>
pblk_gc_stop just sets pblk->gc->gc_active to zero, ignoring
the flush parameter. This is plain confusing, so remove the
function and set the gc active flag at the call points instead.
