Hi all,
Today's linux-next merge of the rust tree got a conflict in:
include/uapi/linux/android/binder.h
between commits:
432ff1e91694 ("binder: BINDER_FREEZE ioctl")
ae28c1be1e54 ("binder: BINDER_GET_FROZEN_INFO ioctl")
a7dc1e6f99df ("binder: tell userspace to dump current backtrace when detected oneway spamming")
from the char-misc tree and commit:
1fed5dee5fbb ("Android: Binder IPC in Rust (WIP)")
from the rust tree.
I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging. You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

Hah, yeah, it is going to hit this and needs to be fixed up in the rust
code. If they really want this as an enum, we can talk about it :)

If you prefer, I can take out the binder bits from rust-next since
they will be submitted separately anyhow (i.e. they would eventually
go through the char-misc/Android tree after/if Rust support lands).

Miguel

The binder one I can take now if you want to send that to me, as that
would make your development life easier.

It is because bindgen (the tool which generates the "raw" C bindings)
only works with simple C `#define`s. Thus there are two options when
one hits something like this: either copy-paste them manually into the
Rust side (which adds maintenance), or change them into real
objects/identifiers in the C side.
There may be support in the future for expanding macros that end up in
a numeric one: https://github.com/rust-lang/rust-bindgen/issues/753.
Stephen: the resolution looks fine, thanks!

We have two so far: this one (for the RFC Android patch) and another
small one in include/linux/spinlock.h (for the `sync` module).
So far I have put those changes in their respective patches, but if
you prefer I can send them independently too (like the prerequisite
patches).
Cheers,
Miguel

Odd, why does the Rust binder implementation require the IOCTL
definitions to be in an enum instead of a #define?
If that's required, I can take that type of change now to prevent merge
issues in the future.

Hi all,
Today's linux-next merge of the rust tree got a conflict in:
include/uapi/linux/android/binder.h
between commit:
bd32889e841c ("binder: add BINDER_GET_EXTENDED_ERROR ioctl")
from the char-misc tree and commit:
d637f9ec1954 ("[RFC] drivers: android: Binder IPC in Rust")
from the rust tree.
I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging. You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.
