Subject: [PATCH 35/52] y2038: Use a common definition for shmid_ds
Date: Fri, 5 Mar 2021 17:15:01 -0300 [thread overview]
Message-ID: <20210305201518.798584-36-adhemerval.zanella@linaro.org> (raw)
In-Reply-To: <20210305201518.798584-1-adhemerval.zanella@linaro.org>
Instead of replicate the same definitions from struct_shmid64_ds.h
on the multiple struct_shmid_ds.h, use a common header which is included
when required (struct_shmid64_ds_helper.h).
The __USE_TIME_BITS64 is not defined internally yet, although the
internal header is used when building the 64-bit semctl implementation.
