[PATCH v1 0/3] rust: add SRCU abstraction

Posted by Onur Özkan 1 month, 2 weeks ago

The immediate motivation is the Tyr reset infrastructure [1] which needs
to serialize reset sensitive hardware access against reset and teardown
paths. That reset series started to require too many independent dependencies,
so this SRCU support is split out as a standalone Rust API to keep the reset
series focused on the reset logic and easier to review, rebase and land.
