[v3,13/24] y2038: Use a common definition for msqid_ds
Checks
Commit Message
From: Lukasz Majewski <lukma@denx.de>
Instead of replicate the same definitions from struct_msqid64_ds.h
on the multiple struct_msqid_ds.h, use a common header which is included
when required (struct_msqid64_ds_helper.h).
The __USE_TIME_BITS64 is not defined internally yet, although the
internal header is used when building the 64-bit stat implementations.

No regressions on x86_64 and i686 and reviewed resulting ABI for correctness.

OK. Adds reserved entries. Matches kernel.
