1. invokes optional hostt->eh_timed_out() callback. Return value can
be one of
- - BLK_EH_HANDLED
- This indicates that eh_timed_out() dealt with the timeout.
- The command is passed back to the block layer and completed
- via __blk_complete_requests().
-
- *NOTE* After returning BLK_EH_HANDLED the SCSI layer is
- assumed to be finished with the command, and no other
- functions from the SCSI layer will be called. So this
- should typically only be returned if the eh_timed_out()
- handler raced with normal completion.
-
- BLK_EH_RESET_TIMER
This indicates that more time is required to finish the
command. Timer is restarted. This action is counted as a
retry and only allowed scmd->allowed + 1(!) times. Once the
- limit is reached, action for BLK_EH_NOT_HANDLED is taken instead.
+ limit is reached, action for BLK_EH_DONE is taken instead.
- - BLK_EH_NOT_HANDLED
+ - BLK_EH_DONE
eh_timed_out() callback did not handle the command.
Step #2 is taken.
