This is also passed on in hello messages and used to detect if a reboot has occurred. This 'incarnation' is obtained using do_gettimeofday.It is only used in equality checks, so the absolute value does not matter. This patch replaces do_gettimeofday with ktime_get_ns for the following reasons: 1. ktime_get_ns returns a __u64 which is safer than 'struct timeval' which will overflow on 32-bit systems in year 2038 and beyond. 2. Reduced compute: ktime_get_ns is faster than the multiply/add combination used in this function Signed-off-by: Tina Ruchandani Signed-off-by: Greg Kroah-Hartman --- Reading git-diff-tree failed
