Hi,
Sorry, I've been on a leave. Catching up on emails.
In case this is still not yet merged, my comment is
be consist with the new variable name. In some cases
it's "ttm_opt_ctx", in others it's "ctx".
I prefer ttm_opt_ctx because it's more descriptive.
And yes, some description on why this change is necessary in the
commit message is nice, too.
