Hi all To write multiple kernel version compatible programs, I need to know when a specific symbol (a struct or a function)were introduced in to the kernel tree Binary search against multiple kernel sources is a way,but is still slow.Is there any fast way to use modern git technology to make my life easier? Many thanks.
