From: Dave Chinner <dchinner@xxxxxxxxxx>
now most of the infrastructure is in place, we can start adding
support for configuring specific errors such as ENODEV, ENOSPC, EIO,
etc. Add these error configurations and configure them all to have
appropriate behaviours. That is, all will use the "fail never, fail
at unmount" default except for ENODEV, which is an unrecoverable
error so it will be configured as a "fail fast" error.
