__kernel_time_t timestamp;
/* unused, make sure to use atomic time for y2038 if it ever gets used */long timestamp;This change breaks x32 ABI (and possibly MIPS n32 ABI), as __kernel_time_t there is 64 bit already: https://sourceforge.net/p/strace/mailman/message/36015326/
Note the change in structure size from 0x20 to 0x14 for VIDEO_GET_EVENT command in linux/x32/ioctls_inc0.h.
Are you sure it worked before the change? I don't see any handler in the kernel for the x32 compat ioctl call here, only the compat_video_event handling, so my guess is that the change unintentionally fixes x32.
