scsi_device_quiesce(9)

scsi_device_quiesce9

Block user issued commands.

Usage

int scsi_device_quiesce(struct scsi_device * sdev);

Arguments

sdev

scsi device to quiesce.

Overview

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.
