Log Message:
Automatically build up a list of bad sectors from failed read operations and
prempt read operations on matching regions with a failure rather than waiting
for the device to return a failure.  The I/O operation must have already failed
MAXRETRIES times before being added to the list - this can generally take up
to 12 seconds.
List is made accessible to userspace via DIOCBSLIST and DIOCBSFLUSH.
