knfsd: clean up nfsd filesystem interfaces
Several of the nfsd filesystem interfaces allow changes to parameters that don't have any effect on a running nfsd service. They are only ever checked when nfsd is started. This patch fixes it so that changes to those procfiles return -EBUSY if nfsd is already running to make it clear that changes on the fly don't work. The patch should also close some relatively harmless races between changing the info in those interfaces and starting nfsd, since these variables are being moved under the protection of the nfsd_mutex. Finally, the nfsv4recoverydir file always returns -EINVAL if read. This patch fixes it to return the recoverydir path as expected. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: J.
