New Revision: 205661
URL: http://svn.freebsd.org/changeset/base/205661
Log:
Patch the regular NFS server so that it returns ESTALE to the client
for all errors returned by VFS_FHTOVP(). This is required to ensure
that EIO doesn't get returned to the client when ZFS is used as the
server file system.
