)

mpt2sas_transport_done - internal transport layer callback handler. : per adapter object : system request message index : MSIX table index supplied by the OS : reply message frame(lower 32bit addr)

Callback handler when sending internal generated transport cmds. The callback index passed is ioc->transport_cb_idx

Return 1 meaning mf should be freed from _base_interrupt 0 means the mf is freed from this function.

int scsi_internal_device_block ( struct scsi_device *  sdev)

scsi_internal_device_block - internal function to put a device temporarily into the SDEV_BLOCK state : device to block

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.

int scsi_internal_device_unblock ( struct scsi_device *  sdev,
enum scsi_device_state  new_state 
)

scsi_internal_device_unblock - resume a device after a block request : device to resume : state to set devices to after unblocking

Called by scsi lld's or the midlayer to restart the device queue for the previously suspended scsi 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_RUNNING state or to one of the offline states (which must be a legal transition) allowing the midlayer to goose the queue for this device.
