Subject: [PATCH v2 2/4] rust: task: implement == operator for Task
Date: Fri, 27 Feb 2026 09:34:47 +0000 [thread overview]
Message-ID: <20260227-close-fd-check-current-v2-2-b3347edbb310@google.com> (raw)
In-Reply-To: <20260227-close-fd-check-current-v2-0-b3347edbb310@google.com>
It's useful to compare if two tasks are the same task or not. Rust
Binder wants this to check if a certain task is equal to the group
leader of current.
