sys/boot/efi/libefi/time_event.c
1 ↗	(On Diff #17268)	This file wasn't copied, but git seems to think so due to the similar license.

sys/boot/efi/libefi/Makefile
10–14 ↗	(On Diff #17268)	Do you think it would make sense to just use the same code in both cases?
16 ↗	(On Diff #17268)	blank line?
sys/boot/efi/libefi/time_event.c
1 ↗	(On Diff #17268)	Yeah, probably because the non-license-block content in the both the old and new files is rather small.

sys/boot/efi/libefi/Makefile
10–14 ↗	(On Diff #17268)	I didn't because it is untested there. I got the idea from grub where they still use the GetTime functions in x86.
16 ↗	(On Diff #17268)	Merge conflict, should be one line higher
