  To: akpm; +Cc: linux-kernel

Name: MODULE_ALIAS inside modules: block devices
Author: Rusty Russell
Status: Booted on 2.6.0-test4-bk3

D: Previously, default aliases were hardwired into modutils.  Now they
D: should be inside the modules, using MODULE_ALIAS() (they will be overridden
D: by any user alias).
