Probably because it's either too simple or too specific. 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.
