Actually if you could clean up the NFS code that would be great. It's _full_ of set but not used warnings. And anyone else reading this if you could clean up other areas. I've mostly cleaned up kern / net / netinet / iflib drivers. both WITHOUT_FORMAT_EXTENSIONS= XCC=/usr/local/bin/gcc8 make -j<ncpu> buildkernel and WITHOUT_FORMAT_EXTENSIONS= XCC=/usr/local/bin/gcc8 make -j<ncpu> buildkernel KERNCONF=GENERIC-NODEBUG Thanks.
