Then please let me know the name of it.

I have experienced same situation several time. That is, I faced a
problem and asked for it on ML. Then I was told to try some tunable.
So I thought there may be tunable that can be used as workaround in
this case. But for those who isn't familiar with kernel internal, it
it quite hard to find it without knowing its name. If all tunable were
listed with brief explanation in one document, then I saw it and could
pick up possible candidates. But actually they are documented
separately among many man pages. So the first difficulty is to find
man page in which possible tunable may be explained. If the problem is
releted to some device, it is most hopeful to check its man page. But
in this case, even after reading the commit message, I had no idea
which man page to check.
