svn commit: r306835 - user/alc/PQ_LAUNDRY/sys/vm

[Alan Cox]

Author: alc

New Revision: 306835
URL: https://svnweb.freebsd.org/changeset/base/306835

Log:
  Revert one line of r306595.  The variable "shortfall" is reset each time
  that the laundry thread wakes up, so it can't be used to tell if a shortfall
  laundering is in progress.
