>Description:

It is not possible to load nfs4client.ko because kernel linker complains about
some symbols (which are missing):
root at dunstan:/usr/src/sys/modules/nfs4client:# make load
/sbin/kldload -v /usr/src/sys/modules/nfs4client/nfs4client.ko
kldload: can't load /usr/src/sys/modules/nfs4client/nfs4client.ko: No such
file or directory
*** Error code 1

Stop in /usr/src/sys/modules/nfs4client.
root at dunstan:/usr/src/sys/modules/nfs4client:# dmesg | tail -1
link_elf: symbol nfs_writebp undefined

It seems this symbols exist in code shared between nfs4client and nfsclient.

>How-To-Repeat:

# cd /sys/modules/nfs4client/
# make load

>Fix:
Patch [nfs4client.Makefile] corrects this bug by compiling files taken from
nfsclient and linking them to nfs4client.ko. Tested on -STABLE and -CURRENT.
