Hi Alexei,

syzbot tests patches on request. I don't see anybody requested any
testing for this bug. When testing is requested syzbot replies with
results generally within 30 mins. You can read more about patch
testing here:

Finding and reporting bugs is a prerequisite for fixing them and
improving kernel quality. syzbot simply automates that part of bug
handling process, something that otherwise would needed to be done by
kernel developers. But active developer involvement and interest are
still required as not all parts are automatable.
