From 2c8c1e7297e19bdef3c178c3ea41d898a7716e3e Mon Sep 17 00:00:00 2001 From: Alexey Dobriyan Date: Sun, 17 Jan 2010 03:35:32 +0000 Subject: net: spread __net_init, __net_exit __net_init/__net_exit are apparently not going away, so use them to full extent. In some cases __net_init was removed, because it was called from __net_exit code. Signed-off-by: Alexey Dobriyan Signed-off-by: David S.
