Hello, Freebsd-geom.
I'm digging thought GEOM/IO code and can not find place, where
requests from userland to read more than MAXPHYS bytes, is splitted
into several "struct bio"?
It seems, that these children request are issued one-by-one, not in
parallel, am I right? Why? It breaks down parallelism, when
underlying GEOM can process several requests simoltaneously?
