Name
scsi_internal_device_block —
internal function to put a device temporarily into the SDEV_BLOCK state
Synopsis
int scsi_internal_device_block ( | struct scsi_device * sdev); |
Description
Block request made by scsi lld's to temporarily stop all
scsi commands on the specified device. Called from interrupt
or normal process context.
Returns zero if successful or error if not
Notes
This routine transitions the device to the SDEV_BLOCK state
(which must be a legal transition). When the device is in this
state, all commands are deferred until the scsi lld reenables
the device with scsi_device_unblock or device_block_tmo fires.
