Hi,(CC me)
As a newbie i'm kinda expecting flames here... but, I just had to share my thoughts =/
Couldn't the kernel module subsystem work something like this:
When a module is loaded it gets it's own mutex (for shared locks).
Each program/module/kernel part that uses it obtains a lock. If we load a new module that replaces a older module we could have lock migrations to the new module.
This would make sure that all use of the module has ceased before it's removed.
This would also require a "usage count" per module/kernel/program though. But that could be included in the module subsystem imho or am i wrong?
If a module is replaced by a newer/other module how do we manage the transgression to the new module? Well depending on how the sub system works it could be done automagically i think...
One problem with this is that it'll use more memory... And i bet that there are better less complicated ways of doing this but i really think that the modules should be removable, it might take a hour or so (worst case senario) but it should be removed eventually...

PS. This is more or less a brainfart... so there might be huge holes in the idea etc. And don't forget to CC me since i'm not on the list. DS.
