    After looking over these patches, it appears there two 'minor'
    things missing... comments and dprintk statements... :-)
    Maybe I missed them, but out of all these 14 patches (i.e. basically
    rewriting a critical part of kNFSD) not one comment or dprintk
    as added....

    Now I'm sure this is a much better design that the previous one,
    (i.e. hide sight is always 20/20) and I'm looking forward to
    help iron out the nits... But without meaningful comments and a way
    to turn on a _few_ well placed "I failed here" type of debug
    messages, the design really doesn't matter since the maintainable
    has not improved... imho...

    Secondly, In a number of places, mostly in the alloc routines and in
    patch 006 there are if statements like:

    + if (ch)
    + return container_of(ch, struct svc_export, h);
    + else
    + return NULL;
    the else is simply not needed... Plus adding a dprintk like:

    + if (ch)
    + return container_of(ch, struct svc_export, h);
    + dprintk("svc_export_update: returns NULL\n");
    + return NULL;
    might make sense... assuming svc_export_update does not return NULL
    99% of the time...
