The current situation with buffer group id juggling is not ideal. req->buf_index first stores the bgid, then it's overwritten by a buffer id, and then it can get restored back no recycling / etc. It's not so easy to control, and it's not handled consistently across request types with receive requests saving and restoring the bgid it by hand. It's a prep patch that adds a buffer group id argument to io_buffer_select(). The caller will be responsible for stashing a copy somewhere and passing it into the function.
