how to find when a symbol introduced into the kernel

[Zhaohui Wang]

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.

Best Regards
Zhaohui Wang
