Take a look at this FIFO [1] e.g. It handles single network packets, with or without locking dependent on the number of readers/writers. Would look different again if you decide to dequeue more than one packet at a time. Further FIFOs are contained in the 16550A driver, but I do not see urging similarities between all of them. Anyway, if someone drafts a generic FIFO for RTDM, I would definitely welcome this. Would not be the first time users came up with concrete scenarios, and we finally added a useful new feature.
