.SH NAME
scsi_device_quiesce \- Block user issued commands.
.SH SYNOPSIS
"SYNOPSIS"
.sp
\fB
.sp
int scsi_device_quiesce  (struct scsi_device * \fIsdev\fB);
\fR
.SH "ARGUMENTS"
.TP
\fB\fIsdev\fB\fR
scsi device to quiesce.
.SH "DESCRIPTION"
.PP
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.
.PP
Must be called with user context, may sleep.
.PP
Returns zero if unsuccessful or an error if not.
