Author: rmacklem Date: Thu Jul 19 20:58:59 2018 New Revision: 336516 URL: https://svnweb.freebsd.org/changeset/base/336516 Log: MFC: r333766 Add a missing nfsrv_freesession() call for an unlikely failure case. Since NFSv4.1 clients normally create a single session which supports both fore and back channels, it is unlikely that a callback will fail due to a lack of a back channel. However, if this failure occurred, the session wasn't being dereferenced and would never be free'd. Found by inspection during pNFS server development.
