Re: [Minios-devel] [UNIKRAFT PATCH v3 12/12] lib/uksched: Add private field for user



Reviewed-by: Florian Schmidt <florian.schmidt@xxxxxxxxx>

The private field may be used by the user for holding its private
information in scheduling frameworks which would wrap the Unikraft
scheduling functionality. One such example might be the pthread library
which would set the private field as a back pointer to its pthread_t
data. This is especially useful when implementing pthread_self() by
calling uk_thread_current().
