How is anyone supposed to know what that actually refers to? Why doesn't it put the real name (maybe with "upstream" in parentheses as an additional comment)? Furthermore, the last time I tried to submit a test patch with something like "#syz test: upstream 794c7931a242", it didn't work because syzbot itself didn't recognize the repository name! This should already be fixed -- I can't remember when I first reported the problem but it must have been at least two years ago. If there isn't already a change request pending for this issue, can you add one? Thanks, Alan Stern
