Greetings SCSI and virtual filesystem folks,
This patch series contains the initial commits to lio-core-2.6.git/lio-4.0 to
support the new generic fabric module configfs infrastructure for TCM, and
the subsequent changes to drivers/target/lio-target and drivers/target/tcm_loop
to use generic configfs infrastructure from drivers/target/target_core_fabric_configfs.c.
The main idea behind the 4.0 configfs code is that fabric modules can use a generic
set of struct config_item_types and struct config_groups hanging off fabric dependent
structures, without having to explictly define a configfs layout of
/sys/kernel/config/target/$FABRIC themselves. This allows a generic layout to be used with
fabric dependent attributes using struct config_item_type context specific macros in
include/target/target_core_fabric_configfs.h.
This is still a WIP, and this first series allows both lio-target and tcm_loop
fabric modules to run in demo mode (eg: no ACLs) using the generic configfs code.
I am hoping to get some feedback on the current work and any thoughts on possible improvements..
Thanks!
