PATCH 1/1 MODULE_PARM_: remove the __deprecated

Hi Rusty,

I know you will not like this patch, but I consider it important since the current beghavior is pretty annoying.

When making patches here and there, I'm touching many different places in the kernel. One of the advantages of the 2.6 build system is that warnings are very visible - and often a new compile warning indicates that something with the patch is wrong.

MODULE_PARM_ might be deprecated.
But there are still over 2000 places in the kernel where it's used. I consider it _very_ annoying if after changing the kernel, the whole screen is swamped with warnings that MODULE_PARM_ is deprecated as it still happens in several subsystems. That's quite annoying if you want to check whether changing a common header file has any negative effects.

This is not generally against using __deprecated, but currently MODULE_PARM_ generates so many warnings that it's really no fun.

Hi Rusty,

Damn straight. But I never intended this to happen; this patch was one of a series.

I went through and fixed up many of them but naturally such a patch was fragile, huge, and even broke some stuff.

As a result, Andrew dropped the patch, which is fair, but leaves us with the current state.

I'll go through those patches again today and resent against -mm.

Rusty.

Changing MODULE_PARM to module_param is not exactly rocket science. You could probably fix them all with a perl script.

Not really. The permissions for the sysfs files, if nothing else, have to be done manually. Plus, check out:

and

http://lists.osdl.org/pipermail/kernel-janitors/2004-November/002592.html

for two examples of the kinds of problems that a script would run into. Not rocket science, but it can be tricky.

Well for every complex example like yours there is one like this:

You would have to check the results of course.
