Next message: Adrian Bunk: "[2.6 patch] kernel/resource.c: make resource_op static"
Previous message: Adrian Bunk: "[2.6 patch] kernel/sysctl.c: make some code static"
Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

The patch below contains the following cleanups:
- make some needlessly global code static
- net/802/hippi.c: remove the unused global function hippi_net_init
- net/8021q/vlan.c: remove the global variable vlan_default_dev_flags
that was never changed
- drivers/net/net_init.c: remove four unneeded #include's
