However, this driver is not broken > in 2038 since we are only using microseconds portion of the time. > > This patch replaces 'struct timeval' with 'struct timespec64'. We only > need to find elapsed microseconds rather than absolute time, so it's > better to use monotonic time, so using ktime_get_ts64() makes the code > more efficient and more robust against concurrent settimeofday() > calls. > > Signed-off-by: Amitoj Kaur Chawla <amitoj1606@...il.com> > Reviewed-by: Arnd Bergmann <arnd@...db.de> Applied.
