LGTM thanks for your continued contributions :) 


For the record, a while back I made a script to parse a bunch of calls that may be interesting to us. You may find it useful (or utterly not useful) in your quest to better rtsan.

Some of these are out of date, or wrong etc, just tried to parse various system headers and man files to throw some things together.
