1. NAME▲

scsi_device_quiesce - Block user issued commands.

2. SYNOPSIS ▲

int scsi_device_quiesce(struct scsi_device *  sdev );

3. ARGUMENTS ▲

sdev
    scsi device to quiesce.

4. 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 doesnAqt guarantee the device will be totally quiescent.

Must be called with user context, may sleep.

Returns zero if unsuccessful or an error if not.
