Subject: perf lock record fails

What config options need to be enabled for 'perf lock record' to work? I 
tried a number of custom builds and stock Fedora kernels. I always get:

$ perf lock record -- sleep 1
invalid or unsupported event: 'lock:lock_acquire'

Though trace_lock_acquire exists, CONFIG_LOCKDEP is set, and ftrace is 
enabled.

What am I missing?
