well, we can either
- revert 11b5fe26f (CHROMIUM: dm: Add support for devices by
PARTUUID/PARTNROFF),
- build it into the kernel (large module!)
- export the symbol in genhd.c
- do something completly different
Looks like a chromium specific hack, but reverting it may cause more harm than
just
exporting the symbol.
Votes?
