The usermode helper declarations were previously provided by linux/kmod.h
but commit c1f3fa2a4fde ("kmod: split off umh headers into its own file")
moved them to linux/umh.h in 2017. Add explicit includes of linux/umh.h to
files that use usermode helpers and remove linux/kmod.h where it is no
longer needed.

Then clean up linux/kmod.h so that it includes only the headers that it
actually requires, importantly removing the compat linux/umh.h include.

Apologies for the wide distribution.

This cleanup is motivated by trying to reduce the preprocessed size of
linux/module.h, which includes linux/kmod.h. The linux/module.h header is
included by every *.mod.c file to provide `struct module` and other related
definitions, so it should avoid pulling in unnecessary dependencies. Note
that this series doesn't immediately improve the situation, since most of
the files included by linux/kmod.h are, for now, also included by
linux/module.h through other paths.

in this code.

Thanks,

You're right. I'll remove the kmod.h include from
kernel/cgroup/cgroup-v1.c. I went through all the files again and it
seems this was the only place I missed.

Including linux/kmod.h alone results in 1.5 MB of preprocessed output, even
though it provides only a few functions and macros.

The header currently depends on:

* __printf() -> linux/compiler_attributes.h,
* ENOSYS -> linux/errno.h,
* bool -> linux/types.h.

Include only these files, reducing the preprocessed output to 10 kB.
