# scsi\_internal\_device\_unblock(9)

resume a device after a block request

## NAME

scsi\_internal\_device\_unblock - resume a device after a block request

## SYNOPSIS

**int scsi\_internal\_device\_unblock(struct scsi\_device \*** *sdev***, enum scsi\_device\_state** *new\_state***);**

## ARGUMENTS

*sdev*

device to resume

*new\_state*

state to set devices to after unblocking

## DESCRIPTION

Called by scsi lld's or the midlayer to restart the device queue for the previously suspended scsi device. Called from interrupt or normal process context.

## NOTES

This routine transitions the device to the SDEV\_RUNNING state or to one of the offline states (which must be a legal transition) allowing the midlayer to goose the queue for this device.
