Author: markj
Date: Thu Dec  7 19:38:09 UTC 2017
New revision: 326664
URL: https://svnweb.freebsd.org/changeset/base/326664

Log:
  Fix the UMA reclaim worker after r326347.

  atomic_set_*() sets a bit in the target memory location, so
  atomic_set_int(&uma_reclaim_needed, 0) does not do what it looks like
  it does.
