latch:
library cache lock
library cache lock allocation
library cache pin
library cache pin allocation
library cache

ALL above latches have gone(latch library cache load lock left), library cache lock/pin don't need acquire library cache any more in 11g ;

library cache lock/pin structure now are protected by Library cache type mutex also.
But We can not find out how kglpin/kgllkdl and else function are utlized with mutex from any V$/X$ dynamic views.
Mutex is more black-box than Latch.
