The next patch will split blockdev.c, which will require accessing
some previously-static functions from more than one .c file. But part
of promoting a function to public is picking a naming scheme that does
not reek of exposing too many internals (two of the three functions
were named starting with 'do_'). To make future code motion easier,
perform the function rename and non-static promotion into its own
patch.
