I just went back over the original problem, your proposed fix, and all
of the discussion in this thread.

Sadly, I don't think the patch you have proposed is the right fix.

As Steve has pointed out, the CWD path is the working directory from
which the current process was executed.  I believe we should log the
full path, or as complete a path as possible, in the nametype=CWD PATH
records.  While the nametype=PARENT PATH records have a connection
with some of the other PATH records (e.g. DELETE and CREATE), the
nametype=PARENT PATH records are independent of the current working
directory, although they sometimes may be the same; in the cases where
they are the same, this is purely a coincidence and is due to
operation being performed, not something that should be seen as a
flaw.

>From what I can tell, there are issues involving the nametype=PARENT
PATH records, especially when it comes to the *at() syscalls, but no
issue where the nametype=CWD PATH records have been wrong, is that
correct?
