Author: rmacklem Date: Mon Nov 12 00:23:58 2018 New Revision: 340356 URL: https://svnweb.freebsd.org/changeset/base/340356 Log: Add NFSv4.2 client support for VOP_ADVISE() to sys/fs/nfs. Changes to sys/fs/nfsclient will be done in a separate commit. More needs to be done here, including handling of the stateid and support for NFSv4.2 DSs.
