Hi Mauro,
This series makes the V4L2 API y2038 safe. Many thanks to Arnd for working on
this!
I have tested this using the test-media script and v4l2-ctl/v4l2-compliance
binaries compiled for x86_64, i686, i686 with 64-bit time_t under both a
64 bit kernel (so the compat-ioctl32 code is called) and a native 32 bit
kernel (to make sure both the 32 and 64-bit time_t versions are handled
correctly).
Regards,
Hans
