# scsi\_device\_quiesce(9)

Block user issued commands.

## NAME

scsi\_device\_quiesce - Block user issued commands.

## SYNOPSIS

**int scsi\_device\_quiesce(struct scsi\_device \*** *sdev***);**

## ARGUMENTS

*sdev*

scsi device to quiesce.

## DESCRIPTION

This works by trying to transition to the SDEV\_QUIESCE state (which must be a legal transition). When the device is in this state, only special requests will be accepted, all others will be deferred. Since special requests may also be requeued requests, a successful return doesn't guarantee the device will be totally quiescent.

Must be called with user context, may sleep.

Returns zero if unsuccessful or an error if not.
