scsi_internal_device(9)
NAME
scsi_internal_device_unblock - resume a device after a block request
SYNOPSIS
int scsi_internal_device_unblock(struct scsi_device * sdev);
ARGUMENTS
- sdev
- device to resume
DESCRIPTION
Called by scsi lldīs or the midlayer to restart the device queue for
the previously suspended scsi device. Called from interrupt or normal
process context.
Returns zero if successful or error if not.
NOTES
This routine transitions the device to the SDEV_RUNNING state (which
must be a legal transition) allowing the midlayer to goose the queue
for this device. This routine assumes the host_lock is held upon entry.
