Subject: [PATCH 0/2] Fix two issue between removing device and error handle

I am testing SCSI error handle with my previous scsi_debug error
injection patches, and found two issue when removing device and
error handler happened together.

The first patch fix IO hang because scsi_eh_flush_done_q() would
retry command if the device is in SDEV_CANCEL state;

The second patch fix the issue which device's eh_device_reset_handler
not called in recovery when device is in removing progress.

Wenchao Hao (2):
  scsi: core: scsi_device_online() return false if state is SDEV_CANCEL
  scsi: scsi_error: Fix device reset is not triggered
