[PATCH] Kernel Module Loader vs. v2.5.43

From: Rusty Russell (rusty@rustcorp.com.au)

Changes this version:
  o Updated to 2.5.43
  o Removes the "spurious failure" problem, which could
    theoretically occur during a failed unload attempt. To do this, it
    uses a very lightweight refcount machanism in try_module_get(), and a
    complex machine-stopping maneuver on attempted unload. This solution
    is inspired by discussions with Daniel Phillips.
  o You can use "no_module_init;" instead of declaring an init function.

It passes stress testing on my dual x86 box.

And as one convienent megapatch:


  Anyone who quotes me in their sig is an idiot. -- Rusty Russell.

D: This is an implementation of the in-kernel module loader extending D: the try_inc_mod_count() primitive and making its use compulsory. D: This has the benifit of simplicity, and similarity to the existing D: scheme. To reduce the cost of the constant increments and D: decrements, reference counters are lockless and per-cpu. D: D: Modversions, Module parameters and kallsyms are not supported in D: this patch, they come in future patches. inter_module_get/put have been D: eliminated: use symbol_get() and symbol_put(). D: D: You will need the trivial replacement module utilities from: D: http://www.kernel.org/pub/linux/people/rusty/module-init-tools-0.5.tar.gz
