Are you working on this?  This is the 6th open syzbot report that has been
bisected to this commit, and I suspect it's the cause of many of the other
30 open syzbot reports I assigned to the bpf subsystem too
(https://lore.kernel.org/bpf/20190624050114.GA30702@sol.localdomain/).

Also, this is happening in mainline (v5.2-rc6).
