Alan Somers d565784a7e zfsd: fault disks that generate too many I/O delay events
If ZFS reports that a disk had at least 8 I/O operations over 60s that
were each delayed by at least 30s (implying a queue depth > 4 or I/O
aggregation, obviously), fault that disk.  Disks that respond this
slowly can degrade the entire system's performance.
