Definitely, any analysis that is able to statically prove some
properties would be ideal, and any improvement over what the kernel
has now (whether for C or for Rust) would be welcome.
For debugging sleeps in atomic contexts, there is `might_sleep()` and
friends: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/include/linux/kernel.h#n131
Another area that could be interesting to look at for feasibility of
new analyses is locking correctness, see lockdep:

Indeed.
Cheers,
