Trait kernel::sync::NeedsLockClass

fn init(

key2: &'static LockClassKey
);
}Expand description
A trait for types that need a lock class during initialisation.
Implementers of this trait benefit from the [init_with_lockdep] macro that generates a new
class for each initialisation call site.
Required Methods
fn init(
self: Pin<&mut Self>,
name: &'static CStr,
key1: &'static LockClassKey,
key2: &'static LockClassKey
)
fn init(
self: Pin<&mut Self>,
name: &'static CStr,
key1: &'static LockClassKey,
key2: &'static LockClassKey
)
Initialises the type instance so that it can be safely used.
Callers are encouraged to use the [init_with_lockdep] macro as it automatically creates a
new lock class on each usage.
