io_uring_prep_remove_buffers - prepare a remove buffers request

       The io_uring_prep_remove_buffers(3) function prepares a request for removing previously supplied buffers.

       by bgid.

       These  are  the errors that are reported in the CQE res field. On success, res will contain the number of
       successfully removed buffers. On error, the following errors can occur.

       -ENOMEM
