lockd allows SIGKILL and responds by dropping all locks and restarting the grace period. This functionality has been present since 2.1.32 when lockd was added to Linux. This functionality is undocumented and most likely added as a useful debug aid. When there is a need to drop locks, the better approach is to use /proc/fs/nfsd/unlock_*. This patch removes SIGKILL handling as part of preparation for removing all signal handling from sunrpc service threads.
