Enum syscall::io_uring::v1::KernelOpcode

#[repr(u8)]#[non_exhaustive]pub enum KernelOpcode {
    Waitpid,
    AllocateIoringMemory,
}

The opcodes specific to the kernel.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Waitpid

TODO

AllocateIoringMemory

Allocates memory meant to be shared between an io_uring producer and consumer, managed by the kernel.

offset	not used	BOTH
len	the number of bytes to allocate	BOTH
