It seems that they are creating a framework for developing kernel
modules in rust that can be integrated with the linux kernel.
They haven't tested the performance of a particular rust driver
compared to a C one. This is a bit different from what we did: we
directly ported a C driver to D and integrated it with the
kernel, with negligible performance loss. The 4% performance loss
that was encountered in some situations is due to the fact that
we have D wrappers over C function calls and some macros are
translated as functions that are called at runtime - they are not
inlined -; one thing we still need to do is to test with the
recent link time optimizations (LTO) and profile guided
optimizations (PGO) flags in clang; we are confident that this
will enhance the performance of the ported driver).
