From 7e75f6077074a7ce2c62092acbad0665ba88485d Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 10 Nov 2017 16:37:09 +0100 Subject: [PATCH] scsi: bfa: use ktime_get_real_ts64 for firmware timestamp BFA_TRC_TS() calculates a 32-bit microsecond timestamp using the deprecated do_gettimeofday() function. This overflows roughly every 71 minutes, so it's obviously not used as an absolute time stamp, but it seems wrong to use a time base for it that will jump during settimeofday() calls, leap seconds, or the y2038 overflow. This converts it to ktime_get_ts64(), which has none of those problems but is not synchronized to wall-clock time. Signed-off-by: Arnd Bergmann Acked-by: Anil Gurumurthy Signed-off-by: Martin K.
