Pavel Begunkov ef49027529 io_uring/cmd: introduce io_uring_cmd_import_fixed_vec 
io_uring_cmd_import_fixed_vec() is a cmd helper around vectored
registered buffer import functions, which caches the memory under
the hood. The lifetime of the vectore and hence the iterator is bound to
the request. Furthermore, the user is not allowed to call it multiple
times for a single request.
