That sounds more like a hybrid between a ring buffer (a data
structure) and a fifo (an IPC mechanism). I think there's value for a
generic buffer for bytewise streamlike data which isn't tied to a
particular idea of syncronization. Maybe split them up and have a
"stream" IPC abstraction that the user can wrap around a ring buffer
they provide?
User can always add a semaphore. Or specify K_NO_WAIT as a timeout value.
