Subject: Re: [PATCH] USB: usbmon: Use 64bit timestamp for mon_bin_hdr
Date: Mon, 4 May 2015 23:37:13 -0700	[thread overview]
Message-ID: <CAB__kkntYHar4yH3hEUFTn3UaXmQTu8qurVCuTeueVS9DVHdUg@mail.gmail.com> (raw)

The 32-bit timestamp obtained using do_gettimeofday() will overflow in
year 2038. However, with 64-bit timestamps, we get practically
infinite time. mon_bin_hdr already has support for a 64-bit seconds
timestamp. This patch changes how it is populated.

Thanks,
Tina
