New Revision: 236875
URL: http://svn.freebsd.org/changeset/base/236875
Log:
MFC r236572:
Replace the use of wall clock time with monotonically increasing
clock. In general, gettimeofday() is not appropriate interface
when accounting for elasped time because it can go backward, in
which case the policy code could errornously consider the limit
as exceeded.
