Hopefully this will get us more up-to-date VMs.

Subject: [PATCH 05/22] Fix some bugs with multithreaded tests:

* kmod tests must run exclusively, because they load and unload a module
  with a constant name.
* A few tests were doing some variant of chdir, but weren't taking the
  CWD_MTX.
* The kmod tests read files by path relative to CWD, so they need the
  CWD_MTX.  But they don't need it exclusively, so convert the CWD_MTX
  into an RwLock.
* Tests that do change the cwd need to change it back when they're done.

Subject: [PATCH 09/22] Skip the af_alg tests in Cirrus CI

I don't know why they fail.  It's probably either a kernel bug or an
undocumented restriction.  According to /proc/crypto these algorithms
_are_ supported on Cirrus's VMs.
