Greeting James and co,

I noticed that the bit wrt to the kernel level target mode fabric
independent configfs infrastructure is not mentioned in the above..

http://marc.info/?l=linux-scsi&m=127010303618447&w=2

Where would this best fit in..?

"A virtual filesystem driven by userspace syscalls to represent a target
HBA/DEV model on top upstream Linux storage subsystems for fabric
modules using a generic set of configfs struct config_groups to
represent target mode fabric endpoints (WWN+TPG+LUN) designed to allow
each their own set of fabric dependent attributes on top of a generic
kernel infrastructure.

The model is to allow the Linux VFS to handle the TCM core HBA/DEV logic
and both fabric independent and dependent data structure dependencies
between LKMs in order to simplify the conversion of existing and
creation of new target mode fabric code."

Best,
