I am little confused here.

Background info:
------
(1) When I said we do _not_ need pp_rdac, I am referring to path
priority callout code(the code I submitted on May 21st). Code under the
directory path_priority/pp_rdac.

(2) The path checker code I submitted on March 23rd is needed to support
the LSI Engenio hardware. This code resides in libcheckers/rdac.c
------

(2) is needed and I presume you are referring to that at (A) 

(1) is not needed and we can achieve the same with
path_priority/pp_tpc/mpath_prio_tpc
