What is the use of function size in linux kernel?

kernel oops shows info about RIP in the format of function() + offset/size but I have not found the 'size' info useful in debugging so far. As far as I know it is a static value defined by compiler/linker and has little to do with stack.
So in what situation would that be helpful or is it sort of redundant?

Have you seen this post? The first is offset from the beginning of the function and the second is total length of the function. Do you need the explanation how knowing the length of a function can be useful?

Thanks and yes I have checked that. Any idea what is the use of function length? seems to me the offset + file symbol is good enough to root cause those issues.
