SYNOPSIS

9       int scsi_internal_device_unblock(struct scsi_device * sdev,
10                                        enum scsi_device_state new_state);

ARGUMENTS

13       sdev
14           device to resume
15
16       new_state
17           state to set devices to after unblocking
18

DESCRIPTION

20       Called by scsi lld's or the midlayer to restart the device queue for
21       the previously suspended scsi device. Called from interrupt or normal
22       process context.
23
24       Returns zero if successful or error if not.
25

NOTES

27       This routine transitions the device to the SDEV_RUNNING state or to one
28       of the offline states (which must be a legal transition) allowing the
29       midlayer to goose the queue for this device.
