RE: [PATCH 1/1] staging: hv: Add Time Sync feature to hv_utilsmodule

[Haiyang Zhang]

> Why a maximum of 50 samples?
After reboot the flag ICTIMESYNCFLAG_SYNC is included in the 
first time message after the timesync channel is opened. Since the 
hv_utils module is loaded after hv_vmbus, the first message is usually
missed. The other thing is, systime is automatically set to emulated 
hardware clock which may not be UTC time or the same time 
zone. So, to override these effects, we use the first 50 time samples 
for initial system time setting.

Thanks for the optimization, I will put it into the code.
