[PATCH] rust: remove unnecessary #includes

[PATCH] rust: remove unnecessary #includes

[Tamir Duberstein]

Commit e26fa546042a ("rust: kbuild: auto generate helper exports")
removed the need for these by automatically generating the exports; it
removed the explicit uses of EXPORT_SYMBOL_GPL but didn't remove the
header includes.

I was about to send the same patch. You have been faster. Thanks! :)

Two nits:

* Theoretically the grammer fix in exports.c could go into an 
independent patch. But if not it at least should be mentioned in the 
commit message. Let Miguel decide if he wants an extra patch or not ;)

* Maybe a

Fixes: e26fa546042a ("rust: kbuild: auto generate helper exports")

tag could be added? Even though Miguel might route it through 
rust-next as its not urgent for routing through rust-fixes.

Anyhow, regarding the main change:

Indeed, in general, one should not have unstated/unrelated changes.

I think this is a cleanup, i.e. just unnecessary `#include`s being
present, right? In other words, there is no "bug" apart from not being
optimal (one could see cleanups as things that should have been done,
but I guess we should draw the line somewhere).

Andreas: was there a reason to keep those `#include`s, just in case?

Thanks!

Cheers,
Miguel

FWIW already not all files in rust/helpers/ had these `#include`s,
e.g. `uaccess.c`.

Thanks for calling out the grammar fix, I'll state that in v2. Should I split it
into a separate patch?

Yes, please (ideally as an independent patch, i.e. it does not need to
be in the same series).

[PATCH v2] rust: remove unnecessary header includes

[Tamir Duberstein]

Commit e26fa546042a ("rust: kbuild: auto generate helper exports")
removed the need for these by automatically generating the exports; it
removed the explicit uses of `EXPORT_SYMBOL_GPL` but didn't remove the
`#include <linux/export.h>`s.

I don't think so, it looks like they should have been removed with
Gary's patch that did the auto export.
