pre-patch-2.1.107 breaks kmod

The pre-patch-2.1.107 in the testing dir on www.kernel.org
contains a diff which brackets the core of request_module()
in kmod.c with a down and an up of a mutex "kmod_sem".

I don't know what problem the mutex is supposed to solve,
but this change makes kmod non-reentrant and unreliable.

My machine deadlocks during boot because eth0 is aliased to ne,
whose init_module() calls request_module("8390") => deadlock!
