The description, from Dan Bungert, follows:

Attempting to use the Reader class with python3.10, such as documented in the
example at
https://www.freedesktop.org/software/systemd/python-systemd/journal.html?highlight=reader#systemd.journal.Reader,
results in the following traceback

File "/usr/lib/python3/dist-packages/systemd/journal.py", line 376, in this_boot
self.add_match(_BOOT_ID=bootid)
File "/usr/lib/python3/dist-packages/systemd/journal.py", line 244, in add_match
super(Reader, self).add_match(arg)
SystemError: PY_SSIZE_T_CLEAN macro must be defined for '#' formats

I have sent a MR that should help, using a cherry-picked commit from upstream.

This issue currently breaks fail2ban for me, which is now defaulting to
python3.10 (via the default python3 dependency).
