From 7457b7eef8dfe8cc48e55b9f9837df6dd397b80d Mon Sep 17 00:00:00 2001 From: Aurelien Jarno Date: Tue, 1 Nov 2022 20:43:55 +0100 Subject: linux: Fix fstatat on MIPSn64 (BZ #29730) Commit 6e8a0aac2f883 ("time: Fix overflow itimer tests on 32-bit systems") changed in_time_t_range to assume a 32-bit time_t. This broke fstatat on MIPSn64 that was using it with a 64-bit time_t due to difference between stat and stat64. This commit fix that by adding a MIPSn64 specific version, which bypasses the EOVERFLOW tests.
