nfsd: Fix nfsd leaks sunrpc module references
Stefan Hajnoczi reports,
nfsd leaks 3 references to the sunrpc module here:
# echo -n "asdf 1234" >/proc/fs/nfsd/portlist
bash: echo: write error: Protocol not supported
Now stop nfsd and try unloading the kernel modules:
# systemctl stop nfs-server
# systemctl stop nfs
# systemctl stop proc-fs-nfsd.mount
# systemctl stop var-lib-nfs-rpc_pipefs.mount
# rmmod nfsd
# rmmod nfs_acl
# rmmod lockd
# rmmod auth_rpcgss
# rmmod sunrpc
rmmod: ERROR: Module sunrpc is in use
# lsmod | grep rpc
sunrpc 315392 3
It is caused by nfsd don't cleanup rpcb program for nfsd
when destroying svc service after creating xprt fail.
