Both the prefetch threads and actual repair processing threads can have multiple buffers at a time locked, but they do no use a common locker order, which can lead to ABBA deadlocks while trying to lock the buffers. Switch the prefetch code to do a trylock and skip buffers that have already been locked to avoid this deadlock.
