[RFC] Forcing 64-bits __OFF_T_TYPE and __INO_T_TYPE for new 32-bit architectures?

["Manuel A. Fernandez Montecelo" <manuel dot montezelo at gmail dot com>]

Hi,

When discussing how to implement these types for the RISC-V architecture
(32, 64 and 128-bit flavours), it seems that there's a drive [1][2] to
force new arches to use the 64-bit versions of these types (so they
would be the same as __OFF64_T_TYPE and __INO64_T_TYPE), even for 32-bit
arches.

Does this look like a reasonable approach?

[1] At least from people in the Linux kernel community.

[2] A further suggestion was that all new arches should default to have
   the same width for these types, 64 bits, and override __OFF_T_TYPE
   and __INO_T_TYPE for all the existing architectures where they are
   currently 32-bits.  I don't know if this is desirable at this point.


Cheers.
