New Revision: 191145
URL: http://svn.freebsd.org/changeset/base/191145
Log:
Added a field to the SVCXPRT structure that the nfsv4 server can
use to identify if the socket is the same one that a cached request
came in on. It is set by nfsrvd_addsock() to a unique value generated
by incrementing an unsigned 64bit static variable for each assignment
and then the value of xp_sockref is tested to see if it is equal to
the value that was saved with the cached reply.
