Maybe you refer to much earlier commit, not mentioned here which was on
the list since February and committed indeed around April 22, so it gave
around 2 months of time for review. In the meantime the patch was
changing although since v6 (beginning of April [1]) it was almost
untouched, except one string change.

Therefore this original set, not one being mentioned here bb17d110cbf2,
was quite available. And you were Cc-ed since beginning - the version 2
this year (February, [2]). Two months is usually quite enough for
review, especially for not so big diff.
