From 81ed334f67e0c56ff0a89ade0fc156c0ba23f190 Mon Sep 17 00:00:00 2001 From: Dmitry Chestnykh Date: Sun, 25 Feb 2024 14:43:28 +0300 Subject: Add support for using time64 on big-endian machines. For BE architectures there is one significant difference in comparison with time64 support for little-endian architectures like ARMv7. The difference is that we strictly need to pass two 64bit values to system calls because Linux Kernel internally uses `struct __kernel_timespec` and similar, which consists of two 64bit fields. For this reason many files have been changed to convert pointers to timespec-family structures (mixed of 64bit and 32bit values) to the pointer of the similar but 64bit-only structures for using as system calls args. This is general prerequisite for any BE architecture.
