It will be pushed if I get no objections before 03/14/22. 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 This queued commit can be viewed at: https://github.com/kevintraynor/dpdk-stable/commit/c77572d2a1f816360cd92b6738821e81ec7c3d18 Thanks. Kevin --- >From c77572d2a1f816360cd92b6738821e81ec7c3d18 Mon Sep 17 00:00:00 2001 From: Bing Zhao Date: Wed, 2 Mar 2022 09:57:35 +0200 Subject: [PATCH] net/mlx5: remove unused reference counter [ upstream commit cff6aad7af61da8d31e146610f9b4a4875301ef4 ] In the previous implementation, a count was used to record the number of the references to a table resource, including the creation of the table, the jumping to the table and the matchers created on the table. Before releasing the table resource via the driver, it needed to ensure that there is no reference to this table. After the optimization of the resources management, the reference count now is in the hash list entry as a unified solution for all the resources management. There is no need to keep the "refcnt" in the table resource structure. It is removed in case that there is some unnecessary memory overhead.
