My impression is that the dev_t part is not complete;
there are some inconsistencies.
(I don't see a compelling reason to change it at all, but
I agree that if there was one, it would be wise to
piggyback it onto the "struct stat" change happening anyway.)
-major()/minor() return 64-bit numbers now, but calculations
 are done with ints and 32 bits elsewhere in the kernel.
 Imho it would be better to leave major and minor numbers
 alone for now - for now only 12/20 bits are used anyway,
 and any change here would require a lot more compatibility
 considerations. And use of 64-bit arithmetics where not
 necessary is wasteful, at least on 32-bit machines.
-Likewise, major numbers should not use NODEV as special
 value. This is a different namespace.
-config(1) mixes build host and target definitions, in
 particular a host's PRIxx format letter is used in
 target context, and "long long" is assumed to match dev_t.
 At a first glance, it might be feasible to avoid
 calculations with the target's full dev_t within config(1)
 completely, just pass major and minor numbers around. Needs
 to be checked.

best regards
Matthias
