This comment should be preserved in some way.  In addition, removing
get_user_pages_locked() makes it harder (compared to a simple "git grep
-w") to identify callers that lack allow-retry functionality).  So I'm
not sure about the benefits of these patches.

If all callers were changed, then sure removing the _locked suffix would
be a good idea.
