 	Show lock contention only for given lock types (comma separated list).
 	Available values are:
 	  semaphore, spinlock, rwlock, rwlock:R, rwlock:W, rwsem, rwsem:R, rwsem:W,
-	  rtmutex, rwlock-rt, rwlock-rt:R, rwlock-rt:W, pcpu-sem, pcpu-sem:R, pcpu-sem:W,

 	Note that RW-variant of locks have :R and :W suffix.  Names without the
 	suffix are shortcuts for the both variants.  Ex) rwsem = rwsem:R + rwsem:W.
