The previous patch I wrote for reclaiming unlinked dinodes
had some shortcomings and did not prevent all hangs.
This version is much cleaner and more logical, and has
passed very difficult testing.  Sorry for the churn.

Right now quirks are printed only when the are manually overriden with
the module parameters. It's not so useful to remind the user that his
parameters are correctly applied; what is useful is to print out the
quirks the user is not aware are being applied.
