From df6a20673011e89f7fbe3d667eee0a9550679841 Mon Sep 17 00:00:00 2001 From: Simon Horman Date: Thu, 21 May 2015 12:40:17 +0900 Subject: [PATCH] rocker: make rocker_port_internal_vlan_id_{get, put}() non-transactional The motivation for this is that rocker_port_internal_vlan_id_{get,put} appear to only partially implement the transaction model: memory allocation and freeing is transactional, but hash and bitmap manipulation is not. The latter could be fixed, however, as it is not currently exercised due to trans always being SWITCHDEV_TRANS_NONE it seems cleaner to make rocker_port_internal_vlan_id_get non-transactional. This problem was introduced by c4f20321d968 ("rocker: support prepare-commit transaction model"). Found by inspection. I do not believe that this change should have any run-time effect.
