Subject: pps: generators: Use ktime_get_real_ts64() instead of ktime_get_snapshot()
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=fe1159fe49b40f73de88d2c29200c813952e061f;p=thirdparty%2Fkernel%2Flinux.git

pps: generators: Use ktime_get_real_ts64() instead of ktime_get_snapshot()

There is no reason to use the more complex ktime_get_snapshot() for
retrieving CLOCK_REALTIME.

Just use ktime_get_real_ts64(), which avoids the extra timespec64
conversion as a bonus.

No functional change intended.
