From c6e359dbc7bd155b10e15616d11e15c48b8bbefa Mon Sep 17 00:00:00 2001 From: Dmitry Chestnykh Date: Wed, 28 Feb 2024 11:45:09 +0300 Subject: libc: Pass 64bit-only time structures to syscalls. With time64 enabled we need to pass structure which consists of two 64bit fields to clock_gettime64() and clock_nanosleep_time64() syscalls with proper conversion to regular timespec structure after syscall execution.
