| Doc Text: |
Deleting an SCSI (Small Computer System Interface) device attached to a device handler caused applications running in user space, which were performing I/O operations on that device, to become unresponsive. This was due to the fact that the SCSI device handler's activation did not propagate the SCSI device deletion via an error code and a callback to the Device-Mapper Multipath. With this update, deletion of an SCSI device attached to a device handler is properly handled and no longer causes certain applications to become unresponsive.
