fn futimens(&self, id: usize, times: &[TimeSpec]) -> Result<usize>

fn recv_io_uring_raw(&self, ctx: Ctx, info_buf: &[u8]) -> Result<usize>

The raw syscall invoked by the kernel when the scheme is requested to have an io_uring attached. This function will most likely not be needed directly, but rather the convenience wrapper recv_io_uring.

fn recv_io_uring(&self, ctx: Ctx, info: &IoUringRecvInfo) -> Result<usize>

Called by the kernel when a userspace program has invoked attach_iouring onto an fd owned by this scheme. The return value is expected to be zero in case the scheme accepted the io_uring, or one otherwise.

fn close(&self, id: usize) -> Result<usize>
