Subject: [PATCH 2/2] MAINTAINERS: add rust bindings entry for bitmap API 

From: Yury Norov [NVIDIA] <yury.norov@...il.com>

This entry enumerates all bitmap and related APIs that rust requires
but cannot use directly (i.e. inlined functions and macros).

The "Rust kernel policy" (https://rust-for-linux.com/rust-kernel-policy)
document describes the special status of rust support:

  "Exceptionally, for Rust, a subsystem may allow to temporarily
   break Rust code."

Bitmap developers do their best to keep the API stable. When API or
user-visible behavior needs to be changed such that it breaks rust,
bitmap and rust developers collaborate as follows:
 - bitmap developers don't consider rust bindings as a blocker for the
   API change;
 - bindings maintainer (me) makes sure that kernel build doesn't break
   with CONFIG_RUST=y. This implies fixes in the binding layer, but not
   in the rust codebase;
 - rust developers adopt new version of API in their codebase and remove
   unused bindings timely.
