BTW, you seem to be using links in a funny way. You set the IOSQE_IO_LINK on the start of a link chain, and then the chain stops when you _don't_ have that flag set. You just set it on everything, then work-around it with a NOP? For this example, only the poll should have IOSQE_IO_LINK set, accept and read should not. This isn't causing your issue, just wanted to clarify how links are used. -- Jens Axboe
