Hi Pavel,
Experimenting with this stuff lets me wish to have a way to have a different 'user_data' field for the notif cqe, maybe based on a IORING_RECVSEND_ flag, it may make my life easier and would avoid some complexity in userspace... As I need to handle retry on short writes even with MSG_WAITALL as EINTR and other errors could cause them. What do you think?
Any comment on this? IORING_SEND_NOTIF_USER_DATA could let us use notif->cqe.user_data = sqe->addr3; metze
