Subject: [PATCH 4/9] lightnvm: pblk: start gc if needed during init
Date: Tue, 3 Oct 2017 12:05:08 +0200 [thread overview]
Message-ID: <1507025113-13351-5-git-send-email-hans.ml.holmberg@owltronix.com> (raw)
In-Reply-To: <1507025113-13351-1-git-send-email-hans.ml.holmberg@owltronix.com>
From: Hans Holmberg <hans.holmberg@cnexlabs.com>
Start GC, if needed, directly after init, as we might
need to garbage collect to make room for user writes.
