From b2cdadde4d5c2b49b0f486a141ae0443ab8be375 Mon Sep 17 00:00:00 2001 From: Lukasz Majewski Date: Tue, 8 Sep 2020 10:54:35 +0200 Subject: Y2038: nptl: Provide futex_abstimed_wait64 supporting 64 bit time This is the helper function, which uses struct __timespec64 to provide 64 bit absolute time to futex syscalls. The aim of this function is to move convoluted pre-processor macro code from sysdeps/nptl/lowlevellock-futex.h to C function in futex-internal.c The futex_abstimed_wait64 function has been put into a separate file on the purpose - to avoid issues apparent on the m68k architecture related to small number of available registers (there is not enough registers to put all necessary arguments in them if the above function would be added to futex-internal.h with __always_inline attribute).
