Author: rmacklem Date: Wed Apr 20 23:25:18 2011 New Revision: 220906 URL: http://svn.freebsd.org/changeset/base/220906 Log: Add a check for VI_DOOMED at the beginning of nfscl_request() so that it won't try and use vp->v_mount to do an RPC during a forced dismount. There needs to be at least one more kernel commit, plus a change to the umount(8) command before forced dismounts will work for the experimental NFS client.
