So I thought changing 4k to 64k would lose some test coverage, the normal 4k pagesize case is lost. > > > do_mkfs > > > if [ $dbsize -ge 1024 ];then > > > blsize="$((dbsize / 1024))k" > > > fi > > > do_test "" pass "allocsize" "false" > > > -do_test "-o allocsize=$blsize" pass "allocsize=$blsize" "true" > > > +do_test "-o allocsize=64k" pass "allocsize=64k" "true" > > > > do_test "-o allocsize=PAGESIZE" pass "allocsize=PAGESIZE" "true" > > > > And do_test converts the "PAGESIZE" to actual page size. > > I thought about that too, but due to this case only uses PAGESIZE once > at here.

The case just trys to make sure 4k/64k can be parsed by > fs_parse(). If it only wants to make sure fs_parse() could parse the arg, then I'm fine with the fix.
