From: Kevin Traynor <ktraynor@redhat.com> To: Long Li <longli@microsoft.com> Cc: Matan Azrad <matan@nvidia.com>, dpdk stable <stable@dpdk.org> Subject: [dpdk-stable] patch 'net/vdev_netvsc: fix device probing error flow' has been queued to LTS release 18.11.11 Date: Wed, 18 Nov 2020 16:35:52 +0000 Message-ID: <20201118163558.1101823-66-ktraynor@redhat.com> (raw) In-Reply-To: <20201118163558.1101823-1-ktraynor@redhat.com> Hi, FYI, your patch has been queued to LTS release 18.11.11 Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet. It will be pushed if I get no objections before 11/24/20. So please shout if anyone has objections. Also note that after the patch there's a diff of the upstream commit vs the patch applied to the branch. This will indicate if there was any rebasing needed to apply to the stable branch. If there were code changes for rebasing (ie: not only metadata diffs), please double check that the rebase was correctly done. Queued patches are on a temporary branch at: https://github.com/kevintraynor/dpdk-stable-queue This queued commit can be viewed at: https://github.com/kevintraynor/dpdk-stable-queue/commit/e304c6da914b1a70d6bfb5ef9f58be5dd14ed943 Thanks. Kevin. --- From e304c6da914b1a70d6bfb5ef9f58be5dd14ed943 Mon Sep 17 00:00:00 2001 From: Long Li <longli@microsoft.com> Date: Thu, 22 Oct 2020 01:11:34 -0700 Subject: [PATCH] net/vdev_netvsc: fix device probing error flow [ upstream commit 702b27d3fc4b82643d08d4b072e6d61b6d73e6be ] If a device probe fails, the alarm is canceled and will no longer work for previously probed devices. Fix this by checking if alarm is necessary at the end of each device probe. Reset the alarm if there are vdev_netvsc_ctx created.
