Subject: [PATCH v10 3/7] rust: error: add EDEADLK
Date: Sat, 3 Jan 2026 10:35:50 +0300 [thread overview]
Message-ID: <20260103073554.34855-4-work@onurozkan.dev> (raw)
In-Reply-To: <20260103073554.34855-1-work@onurozkan.dev>
This is needed for the ww_mutex implementation so
we can handle EDEADLK on lock attempts.
