Thanks. I actually messed this up further. That's supposed to be,
'static_branch_likely()', and 'static_branch_unlikely()'. So:

s/static_key_likely()/static_branch_likely()

and

s/static_key_unlikely()/static_branch_unlikely()

The rest of the doc appears to have it correctly. There are a few more
typos in there as well:

1)

s/addtion/addition

2)

"
The inc()/dec() interface is meant to be used exclusively from the
inc()/dec() for a given key.
"

Was supposed to read:

"
The inc()/dec() interface is meant to be used exclusively from the
enable()/disable() interface for a given key.
"

However, I think we should just delete this sentence. As the API
inherently doesn't prevent this. The user just may need to be aware to
properly serialize operations.


Thanks,

-Jason
