Date: Sun, 20 Mar 2016 16:47:28 -0400 (EDT) From: David Miller <davem@...emloft.net> To: ruchandani.tina@...il.com Cc: netdev@...r.kernel.org, arnd@...db.de, linux-kernel@...r.kernel.org, isdn@...ux-pingi.de, y2038@...ts.linaro.org Subject: Re: [PATCH v7] isdn: Use ktime_t instead of 'struct timeval' From: Tina Ruchandani <ruchandani.tina@...il.com> Date: Sat, 19 Mar 2016 11:21:14 -0700 > 'struct timeval' uses 32-bit representation for seconds which will > overflow in year 2038 and beyond. mISDN/clock.c needs to compute and > store elapsed time in intervals of 125 microseconds. This patch replaces > the usage of 'struct timeval' with 64-bit ktime_t which is y2038 safe. > The patch also replaces do_gettimeofday() (wall-clock time) with > ktime_get() (monotonic time) since we only care about elapsed time here. > > Signed-off-by: Tina Ruchandani <ruchandani.tina@...il.com> > Suggested-by: Arnd Bergmnann <arnd@...db.de> > Suggested-by: David Miller <davem@...emloft.net> Applied, thank you.
