[PATCH 09/13] lightnvm: pblk: Kick writer for flush requests

From: Igor Konopko <hidden>
Date: 2019-02-27 17:18:11
Subsystem: the rest · Maintainer: Linus Torvalds

In case when there is no enough sector available in rwb
and there is flush request send we should kick write thread
which is not a case in current implementation. This patch
fixes that issue.
