From af30c0a00aa0d086a820c2ec75544c07611834d7 Mon Sep 17 00:00:00 2001 From: Shraddha Barke Date: Thu, 22 Oct 2015 20:29:54 +0530 Subject: mtd: tests: Replace timeval with ktime_t Changes the 32-bit time type timeval to the 64-bit time type ktime_t, since 32-bit systems using struct timeval will break in the year 2038. Correspondingly change do_gettimeofday() to ktime_get() since ktime_get returns a ktime_t, but do_gettimeofday returns a struct timeval.Here, ktime_get() is used instead of ktime_get_real() since ktime_get() uses monotonic clock.
