scsi_alloc_target9

Allocate a new or find an existing target

Arguments

parent

parent of the target (need not be a scsi host)

channel

target channel number (zero if no channels)

target id number

Return an existing target if one exists, provided it hasn't already gone into STARGET_DEL state, otherwise allocate a new target.

The target is returned with an incremented reference, so the caller is responsible for both reaping and doing a last put
