From 4dbe28c0fabd69842890ba38f185b96664cba26a Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Wed, 28 May 2025 10:34:30 +0200 Subject: [PATCH] rust: add helper for mutex_trylock After commit c5b6ababd21a ("locking/mutex: implement mutex_trylock_nested", currently in the KVM tree) mutex_trylock() will be a macro when lockdep is enabled. Rust therefore needs the corresponding helper. Just add it and the rust/bindings/bindings_helpers_generated.rs Makefile rules will do their thing.
