Re: [Minios-devel] [UNIKRAFT PATCH v2 1/3] arch/time: Add macros for nanoseconds handling

Add macros for printing __nsec and __snsec types.
Add macro that retrieve the subseconds part of the
given nanoseconds.

Maybe you should split this patch also into two or find a different subject line. For now this is too generic and does not tell me what this patch is actually doing.

Other from this, this looks good!
