From 23409bd4a8b051e28d0106c7a83f362617452098 Mon Sep 17 00:00:00 2001 From: Tina Ruchandani Date: Wed, 13 Apr 2016 00:01:40 -0700 Subject: [PATCH] mpt3sas: Remove usage of 'struct timeval' 'struct timeval' will have its tv_sec value overflow on 32-bit systems in year 2038 and beyond. This patch replaces the use of struct timeval for computing mpi_request.TimeStamp, and instead uses ktime_t which provides 64-bit seconds value. The timestamp computed remains unaffected (milliseconds since Unix epoch).
