Cornelia Huck bddabeb71f vfio: ccw: process ssch with interrupts disabled ... commit 3368e547c5 upstream. When we call ssch, an interrupt might already be pending once we return from the START SUBCHANNEL instruction. Therefore we need to make sure interrupts are disabled while holding the subchannel lock until after we're done with our processing.
