Hello,
In RH internal test, the following UAF[1] is triggered at least two times.
From the log, when deleting one scsi_device, pm_request_idle(parent) is
called, so work function is queued on its parent device(scsi_target),
but after the target device is removed & released, the queued work
function isn't drained yet, so finally UAF is triggered.
So it looks like one runtime PM issue.
