From 40abc27066c49b2c13c817154d438431b0303b96 Mon Sep 17 00:00:00 2001 From: Florin Malita Date: Sun, 18 Sep 2005 00:24:12 -0700 Subject: [PATCH] [BOND]: Fix bond_init() error path handling. From: Florin Malita bond_init() is not releasing rtnl_sem after register_netdevice() and before calling unregister_netdevice() (from bond_free_all()) in the exception path. As the device registration is not completed (dev->reg_state == NETREG_REGISTERING), the call to unregister_netdevice() triggers BUG_ON(dev->reg_state != NETREG_REGISTERED).
