Subject: [PATCH v3 0/4] Additional CondVar methods needed by Rust Binder
Date: Thu, 04 Jan 2024 14:02:40 +0000 [thread overview]
Message-ID: <20240104-rb-new-condvar-methods-v3-0-70b514fcbe52@google.com> (raw)
This patchset contains some CondVar methods that Rust Binder needs.
The CondVar type implements a condition variable, and tries to mirror
the API of the CondVar type provided by the Rust standard library [2].
It is implemented using a `wait_queue_head`.
Please see the Rust Binder RFC for usage examples [1].
Users of rust: sync: add `CondVar::notify_sync`:
[PATCH RFC 04/20] rust_binder: add work lists
[PATCH RFC 07/20] rust_binder: add epoll support
[PATCH RFC 08/20] rust_binder: add non-oneway transactions
Users of rust: time: add msecs to jiffies conversion:
[PATCH v2 3/3] rust: sync: add `CondVar::wait_timeout`
[PATCH RFC 15/20] rust_binder: add process freezing
Users of rust: sync: add `CondVar::wait_timeout`:
[PATCH RFC 15/20] rust_binder: add process freezing
This patchset is based on top of Boqun's patch [3] that renames the
existing wait methods to follow the C convention of using the
_interruptable suffix.
