kfifo, a generic userspace FIFO implementation, port from Linux kernel
https://blog.csdn.net/liigo/article/details/100993236
20220224: added ringbuf_t (ring buffer), a simple copy of kfifo removing usage of typeof, which is not available in ANSI C and some ancient C compilers (I'm looking at you, CodeWarrior 5.1).
The original source files come from Linux kernel tree (v5.3):
- https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/lib/kfifo.c
- https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/include/linux/kfifo.h
