Message-Id: <1447684487-25539-14-git-send-email-m@bjorling.me> Date: Mon, 16 Nov 2015 15:34:47 +0100 From: Matias Bjørling <m@...rling.me> To: linux-block@...r.kernel.org, linux-kernel@...r.kernel.org, linux-nvme@...ts.infradead.org, axboe@...com Cc: Javier González <javier@...igon.com>, Javier Gonzalez <javier@...xlabs.com>, Matias Bjørling <m@...rling.me> Subject: [PATCH 13/13] lightnvm: cleanup queue before target removal From: Javier González <javier@...igon.com> This prevents outstanding IOs to be sent for completion to target after the target has been removed. The flow is now: stop new IOs > cleanup queue > remove target.
