These are all the users. Seems to be pretty much u32 (or unsigned int when printing) everywhere.
Ok, I'll the patch then to clarify this and leave the format unchanged.
Another option would be to change the code storing the times there to do:
header->ph_sec = (u32)ts.tv_sec; header->ph_usec = (ts.tv_sec & 0xffffffff00000000ull) | (ts.tv_nsec / NSEC_PER_USEC);and do the reverse on the user space side. This would be both endian- safe and backwards compatible, although rather ugly.
Indeed, thats' quite ugly. I think in the next 90 years we will need some other adjustments to the log format and should be able to include this one with them (e.g. there are only 16 bits for the cpu, considering we have 260+ core CPUs on the market today, might as well overflow that quite soon).
Ok.
