I need to get the current_kernel_time from a pvclock_gtod callback function, which cannot take the lock again. On x86 we are just calling __current_kernel_time() (see arch/x86/xen/time.c:xen_pvclock_gtod_notify). I was introducing the same functionality on ARM, when the maintainers pointed out that it might be better to use struct timespec64 and related functions for future-proofness. To do that I need a version of __current_kernel_time which returns a struct timespec64. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
