From 7ceb2afbd6aee4643056b47156baad6841db8e78 Mon Sep 17 00:00:00 2001 From: Elad Raz Date: Thu, 21 Apr 2016 12:52:43 +0200 Subject: switchdev: Adding complete operation to deferred switchdev ops When using switchdev deferred operation (SWITCHDEV_F_DEFER), the operation is executed in different context and the application doesn't have any way to get the operation real status. Adding a completion callback fixes that. This patch adds fields to switchdev_attr and switchdev_obj "complete_priv" field which is used by the "complete" callback. Application can set a complete function which will be called once the operation executed.
