Abstract
A wrapper operates to store data relating to messages received from a kernel such that kernel-specific data or information is not passed to a module core. The wrapper on receiving data from the module core uses the data stored in the relevant part of the memory to provide the data or information required by the kernel to handle the message. On receiving a message, the kernel begins to process it. At a certain point the wrapper intercepts the message and creates a SCSI data message and a PLUT element comprising a kernel pointer, a core pointer, and a reference counter. The kernel pointer is provided by the kernel and identifies a memory location where implementation-specific information pertaining to the message, pointers to raw data and a SCSI-formatted command descriptor block resides. The reference counter defines the number of times a message will be processed within the core before the related memory can be reused. The wrapper re-formats data and references the result by the core pointer.
