Commit Message

El Mehdi YOUNES Nov. 4, 2025, 5:16 p.m. UTC
This commit introduces the 'rust.scc' and 'rust.cfg' files, adding
them to the 'SRC_URI' of the 'linux-yocto-dev'.

Ideally, these kernel feature files belong in the separate
'yocto-kernel-cache' repository.

However, for the purpose of this RFC series,they are being added directly
to 'meta/recipes-kernel/linux/files/' to allow the entire feature set to
be tested and reviewed in a single repository.

Once this approach is discussed and approved, these files will be
removed and submitted as a separate patch to the 'yocto-kernel-cache'
project.

Indeed, it isn't ideally, it is "must".

There's no reason to hold off sending the fragments to the linux-yocto
list though.

Just split these into two fragments, even here, and definitely for the
linux-yocto send.
