Well, there's been some controversy about that.  The problem is that
it's often not clear if this is long-standing bug, or a bug which is
in a particular subsystem tree --- and if so, *which* subsystem tree,
etc.  So it gets blasted to linux-kernel, and to get_maintainer.pl,
which is often not accurate --- since the location of the crash
doesn't necessarily point out where the problem originated, and hence
who should look at the syzbot report.  And so this has caused
some.... irritation.

What I suggested was to test Linus's tree, and then when a problem is
found, and syzkaller has a reliable repro, to *then* try to see if it
*also* shows up in the LTS kernels.
