From c67dfb299e05a132154b9bfaae4a83de478ffaa9 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Thu, 29 Oct 2009 14:18:24 +0000 Subject: bond: Simplify bond device destruction Manually inline the code from bond_deinit to bond_uninit. bond_uninit is the only caller and it is short. Move the call of bond_release_all from the netdev notifier into bond_uninit. The call site is effectively the same and performing the call explicitly allows all the paths for destroying a bonding device to behave the same way. Signed-off-by: Eric W.
