Subject: [PATCH v2 0/3] rust: serdev: Refactor
Date: Sun, 20 Sep 2026 14:29:56 +0000 [thread overview]
Message-ID: <20260920-rust_serdev_probe_refactor-v2-0-43b855162f5d@posteo.de> (raw)
The following has been changed:
- introduce a new C serdev API to fix race conditions and simplify rust
code. Should also be useful on the C side.
- fix race conditions
- simplify rust code
Signed-off-by: Markus Probst <markus.probst@posteo.de>

Changes in v2:
- fix missing memory barriers in serdev apis
- use `tty_buffer_restart_work` instead of `tty_flip_buffer_push`
- use `tty_buffer_flush_work` instead of exclusively locking the mutex
- add `#[inline]` to `PrivateData::driver_data`
- remove patches for mutable references
- Link to v1: https://patch.msgid.link/20260906-rust_serdev_probe_refactor-v1-0-69cdae0074ec@posteo.de
