Looks to be:

#syz dup: BUG: MAX_STACK_TRACE_ENTRIES too low! (2)

Original thread: https://lkml.kernel.org/lkml/0000000000005ff8b20585395280@xxxxxxxxxx/T/#u

The caller isn't really meaningful for "MAX_STACK_TRACE_ENTRIES too low" bugs,
so I think
https://github.com/google/syzkaller/pull/1332/commits/ccbd11f30158d198e84953b1bb5eaa33464d9311
should be reverted...
