Also, I've run the checker over 2.2.19, and there were a bunch of
issues but they would require some time and effort to inspect. Some
of them are the same as issues reported for 2.4.x. Would it be useful
to report these?

I forgot to mention that these 15 potential errors are only the *new*
ones. Many of the previously reported dereference errors from 2.4.1 are
still there.

Here are some more results from the MC project. These are 16 errors found
in 2.4.1 related to inconsistent use of locks. As usual, if you can

We modified our compiler extension for checking lock consistency and
found 8 more potential errors.
