From b9047726386bb538cf5e4f52a9f04eb556eebc67 Mon Sep 17 00:00:00 2001 From: Deepa Dinamani Date: Wed, 2 Aug 2017 19:51:11 -0700 Subject: ipc: mqueue: Replace timespec with timespec64 struct timespec is not y2038 safe. Replace all uses of timespec by y2038 safe struct timespec64. Even though timespec is used here to represent timeouts, replace these with timespec64 so that it facilitates in verification by creating a y2038 safe kernel image that is free of timespec. The syscall interfaces themselves are not changed as part of the patch. They will be part of a different series.
