Subject: [PATCH 02/28] lightnvm: handle submit_io failure
Date: Fri, 6 May 2016 20:02:55 +0200 [thread overview]
Message-ID: <1462557801-24974-3-git-send-email-m@bjorling.me> (raw)
In-Reply-To: <1462557801-24974-1-git-send-email-m@bjorling.me>
The device ->submit_io() callback might fail to submit I/O to device.
In that case, the nvm_submit_ppa function should not wait for
completion. Instead return the ->submit_io() error.
