Re: Patch: linux-2.5.42/kernel/sys.c - warm reboot should not suspend devices

[Eric W. Biederman]

Assuming it is worth it to split remove into 2 parts, we need
the following so rmmod calls ->shutdown.  Otherwise we will get
code duplication in the drivers.

And then we need all of the patches that split remove into 2 parts,
in the drivers.
