ok, as long as we don't rush into removing the code, this is an 
acceptable plan. We can discuss the issue further when we meet 
face-to-face next month. In the mean time, will go ahead to make lookup 
code consistent by tentatively putting no_formal_ino aside. Without the 
changes, half of the current NFS lookups would fail. We need to have 
something working right now.

I also invite Kent Baxley (one of our TAMs) here to help out with the 
issue. I recalled he mentioned sometime ago that the "create" table in 
GFS2-mySQL benchmark was noticeably slow - not sure whether 
pick_formal_ino() plays any role there. Will give him two gfs2.ko to 
re-run the benchmark and see what we get.
