Sorry for the response delay, I was waiting to see if Palmer would
merge my KASAN patchset in 6.3 (which he does): I have to admit that
fixing the command line size + the KASAN patchset would allow 6.3 to
run on syzkaller, which would be nice.

If I don't see this merged in 6.3, I'll send another round as you
suggested in 1 week now :)

Thanks!

Alex
