10339ef259 - Fixed empty CREATE_ATTRIBUTES.
- Added version requirement to SCST::SCST.
- Added support for deleting of dynamic attributes.
- Fixed support for changing non-dynamic attributes.
- Fixed (sorta) vcdrom handler.

Still possibly broken:

- Adding/deleting dynamic attributes is a bit broken in my
  SCST tree for some reason. I suspect this may be fixed
  in a later svn commit.

07b012ca56 [PATCH] Session reference count logic error in Qlogic target
When double session is found in q2t_create_sess the session object is updated, 
but after exiting from the function, if the session is not NULL the reference 
counter is decrement, become zero and then the session is deleted. 
As done while making a local session we need here to increment the reference 
count by calling to q2t_sess_get, because at exiting we call to q2t_sess_put.
