New Revision: 282906
URL: https://svnweb.freebsd.org/changeset/base/282906

Log:
  Allow sizeof(cpuset_t) to be queried in capability mode.
  
  This allows functions that retrieve and inspect pthread_attr_t objects to
  work correctly: querying the cpuset_t size is part of querying CPU
  affinity information, which is part of creating a complete pthread_attr_t.
