From 6dcc0cf6cb3120cedc0d4c12171894f3d6415981 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Tue, 18 Nov 2014 08:21:18 -0700 Subject: [PATCH] NVMe: nvme_submit_async_admin_req() must use atomic rq allocation We are called for async event notification issues, and the nvmeq lock is already held. If we fail the request allocation, we'll just retry next time.
