:relfileprefix: ../../
:mrdocs:

The flush error notification is sent to notify the user that an error occurred while flushing block data to disk. Kernel code may ignore flush errors that don't affect the immediate operation it is trying to perform. Applications can choose to handle the flush error notification by logging the error, or notifying the user, or triggering an early shutdown as a precaution against causing more errors.
