Yeah, it seems has _with_mutex() can be better idea.
I'm posting patch, but I noticed that Mark's branch vs Linus branch
have some mismatch (?), and now I'm asking it to him.
I can post _with_mutex() version as v2 if I could get answer.
After that I'm happy your next patch can re-use it.

Thank you for your help !!

Best regards
