From 7ff2819e8dd5b528887dfbe4ff395f5d2142edff Mon Sep 17 00:00:00 2001 From: Deepa Dinamani Date: Wed, 2 Aug 2017 19:51:14 -0700 Subject: ipc: shm: Make shmid_kernel timestamps y2038 safe time_t is not y2038 safe. Replace all uses of time_t by y2038 safe time64_t. Similarly, replace the calls to get_seconds() with y2038 safe ktime_get_real_seconds(). Note that this preserves fast access on 64 bit systems, but 32 bit systems need sequence counters. The syscall interfaces themselves are not changed as part of the patch. They will be part of a different series.
