7

SYNOPSIS

9       int scsi_internal_device_unblock(struct scsi_device * sdev);
10

ARGUMENTS

12       sdev
13           device to resume
14

DESCRIPTION

16       Called by scsi lld's or the midlayer to restart the device queue for
17       the previously suspended scsi device. Called from interrupt or normal
18       process context.
19
20       Returns zero if successful or error if not.
21

NOTES

23       This routine transitions the device to the SDEV_RUNNING state (which
24       must be a legal transition) allowing the midlayer to goose the queue
25       for this device. This routine assumes the host_lock is held upon entry.
