[RFC PATCH 0/3] rust abstractions for interacting with sysfs

[Daniel Sedlak <daniel@sedlak.dev>]

Hello,
For now, there are no facilities for the Rust side to tune modules written
in Rust in runtime or for just simple debug output/statistics from
the module. For exactly this purpose, the C has the sysfs. In this
patch series, I implemented a minimal sysfs wrapper utilizing kobject API.

I would like to collect your thoughts on whether:
  - Do we want something like this in the rust part of the kernel?
  - Do we want to support all sysfs capabilities?

I implemented a sample to present the API I have chosen for the Rust part.
It is a straightforward example that does not represent all capabilities
of the sysfs. The documentation will be potentially improved, but I would
like to first settle the abstractions.

Thank you

Daniel
