Author: Dave Airlie <[email protected]> Date: Sun Mar 21 18:23:22 2010 +1000 gallium: cached bufmgr add map busy check Suggested by Jose on the list, probably not perfect but will let me get past this for now, testing with a fenced bufmgr on top of this, was slower, Also this doesn't let you do the busy early exit optimisation either from what I can see.
