From: Dave Chinner <redacted> 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.
