[DTrace-devel] [PATCH v2] translators: fix io.d.in devinfo_t.dev_{statname, pathname}

[Nick Alcock]

A precedence problem caused us to never accurately determine that
a partitionless device was partitionless, producing erroneous
names like "loop00" for conventional loop devices, etc.

Fixed thusly: translators above 5.12 need regenerating.

Fixes test/unittest/io/tst.{local,wait}.sh.
