We take two values and try to massage them in various
ways. But this function only has one caller and that
puts exactly the same value into both of them. So
simplify the code.

A particular way to do extra-complicated nothing really...  I have stared
at the code for a bit, the flow of "t->options.max_clients" into
"m->max_clients" (assigned exactly once), etc. - and also compared the
logging before/after.

old: MULTI IO: MULTI_IO INIT maxclients=1024 maxevents=1029

new: MULTI IO: MULTI_IO INIT maxclients=1024 maxevents=1029

same numbers ;-)
