From 4e8521333bea6e89fcef1020e59a5f799241c5d4 Mon Sep 17 00:00:00 2001 From: Lukasz Majewski Date: Thu, 15 Oct 2020 09:30:59 +0200 Subject: y2038: Use a common definition for stat Instead of replicate the same definitions from struct_stat_time64.h on the multiple struct_stat.h, use a common header which is included when required (struct_stat_time64_helper.h). The 64-bit time support is added only for LFS support. The __USE_TIME_BITS64 is not defined internally yet, although the internal header is used when building the 64-bit stat implementations.
