Hi everyone,

I'm trying to git-bisect for debugging, but how can I find the tag I need?

for example, I'm find the file change at maybe commit
fc2bd799c7c79c84a59da6f9221370bc6f38c503, how to find the closest tag
for this commit?

This is literally the first link you get on google when searching for
"closest tag for this commit"

https://git-scm.com/docs/git-describe

and a anther question is, is every bisect need to recopmile all kernel
code by `make`? or just need to build the thing I need?

Question is not clear. You need to recompile at each step.
