[PATCH 0/12] Do not include crypto/algapi.h

[PATCH 0/12] Do not include crypto/algapi.h

[Herbert Xu]

Hi:

The header file crypto/algapi.h is for internal use only.  There is
no reason to use it outside of the Crypto API.  Most uses of it
outside of the API should use crypto/utils.h instead.

Feel free to apply this patch to your tree directly.  Just send me
a reply and I'll drop it from my patch queue.

Thanks,

No objection, of course, but I don't think it's necessarily clear that
it "is for internal use only", it literally says:

 * Cryptographic API for algorithms (i.e., low-level API).

which really isn't the same as "don't use this file".

Might want to clarify that, or even move it into crypto/ from
include/crypto/ or something?

Small nit - with the exception of the cookie.c reordering, could you
maintain the existing #include ordering of the other files? No need to
send a v2 for that if you don't want. And please make the entire
commit subject lowercase. With those done,

As a side note, you may want to eventually do something to make sure
people don't add back algapi.h, like move it to internal/ or out of
include/ all together. I figure you've already thought about this, and
this series is just the first step.

Thank you for the patch! It looks good to me:

Acked-by: Matthieu Baerts <matthieu.baerts@tessares.net>

I understood that other patches will come later to make it clear
crypto/algapi.h is for internal use only so that's good!

It is fine for me if you carry this patch in your tree: this part here
has not changed for a while and there is no ongoing work going to modify
it. So there should not be any conflicts when merging the different
trees later.

Yes it should be in include/crypto/internal.  Once the churn gets
small enough I'll move it there.

I was kind of waiting to see - but now that others have applied some
patches to their tree I've done the same.
