The following patches solve the age-old problem - that is, EH eventually
kicking in only after 30 seconds when a disk is removed with active IO.

This series add a new libsas API - sas_device_task_abort() - to abort
device active io and define a interface lldd_device_task_abort() for
LLDD to implement.

Changes since v2:
- Support both for sas and sata device
- Add a new libsas API
- LLDD implement lldd_device_task_abort()

Xingui Yang (3):
  scsi: libsas: Add sas_device_task_abort()
  scsi: libsas: Directly kick-off EH when device removed with active IO
  scsi: hisi_sas: Implement lldd_device_task_abort()
