The syscall number for s390 was added to the kernel at:

test: store coredumps in journal
To make debugging much easier, especially for crashes in tests under
QEMU, let's store the entire coredump bundle in the systemd journal,
which is usually kept around by various CIs. Right now, we usually end
up with a journal, but without the coredump itself, which is pretty
useless.
firstboot: drop duplicate trailing whitespace from root pw question
Since ask_password() (and related calls) already append one char, we
ended up appending two. That's not pretty. Let's fix this, and do it
like in all other cases ask_password() (or an equivalent function) is
called.
networkd: Routes should take the gateway into account
Otherwise, changing the default gateway doesn't purge old gateway routes
left on the system during daemon restart. This also fixes removing other
foreign gateway routes that don't match the expected configuration.
Tested:
Changed gateway addresses prior to the patch and they lingered on
the system during each reconfiguration. Applied this patch and
reconfigured gateways and other routes multiple times and it removed
the foreign routes that had gateways that didn't match.

timedated: always enable&start the service with highest priority
This removes a special case that was implemented before: if some service
was already enabled, we'd treat it as having higher priority.
From https://bugzilla.redhat.com/show_bug.cgi?id=1735584#c4:

timedated: log about unit enablement actions and enhance logs in general
The general idea is that for things which can occur repeatedly, like SetNTP
being called with the same argument, we only log at debug level. For things
which change state, like when we realize that a unit that wasn't enabled
before needs to be enabled, we log at info level.
Also, don't return success if there are no units loaded.
meson: create (empty) /etc/systemd/system during installation
We explicitly create /etc/systemd/user and other parts of the basic directory
tree. I think we should create /etc/systemd/system too. (The alternative would
be to not create those other directories too, but I think it's nice to have
the basic directory structure in place after installation.)
The `coproc` implementation seems to be a little bit different in older
bash versions, so the `strace` is sometimes started AFTER `systemctl
daemon-reload`, which causes unexpected fails. Let's help it a little by
sleeping for a bit.
test: support MPOL_LOCAL matching in unpatched strace versions
The MPOL_LOCAL constant is not recognized in current strace versions.
Let's match at least the numerical value of this constant until the
strace patch is approved & merged.
libsystemd-network: make option_append() atomic and make the code a bit clearer
Comparisons are done in the normal order (if (need > available), not if (available < need)),
variables have reduced scope and are renamed for clarity.
The only functional change is that if we return -ENAMETOOLONG, we do that
without modifying the options[] array.
I also added an explanatory comment. The use of one offset to point into three
buffers is not obvious.
Coverity (in CID#1402354) says that sname might be accessed at bad offset, but
I cannot see this happening. We check for available space before writing anything.
time-util: improve detection of synchronized clock
Instead of checking for the STA_UNSYNC flag in the timex status, check
the maximum error. It is updated by the kernel, increasing at a rate of
500 ppm. The maximum value is 16 seconds, which triggers the STA_UNSYNC
flag.
This follows timedatex and allows timedated to correctly detect a clock
synchronized by chronyd when configured to not synchronize the RTC.
test: print an error when networkctl returns an unexpected EC
If networkctl crashes, like recently with SIGABRT, it returns absolutely
no output, which may be confusing during debugging. Help it a little
with a short informative message.
test-execute: skip test_exec_systemcallfilter_system under ASan
This particular test case keeps intermittently failing due to crashing
LSan when running under clang+ASan. Generally, sanitizers don't
like seccomp filters, so the best option here is to just switch this
test off for this scenario.
`adduser` is in certain cases a standalone package which provides a
better user experience. In other cases it's just a symlink to `useradd`.
And some distributions don't have `adduser` at all, like Arch Linux.
Let's use the `useradd` binary instead, which should provide the same
functionality everywhere.
v2:
- do not watch mtime of transient and generated dirs
We'd reload the map after every transient unit we created, which we don't
need to do, since we create those units ourselves and know their fragment
path.
This reworks how we load units from disk. Instead of chasing symlinks every
time we are asked to load a unit by name, we slurp all symlinks from disk
and build two hashmaps:
1. from unit name to either alias target, or fragment on disk
(if an alias, we put just the target name in the hashmap, if a fragment
we put an absolute path, so we can distinguish both).
2. from a unit name to all aliases
Reading all this data can be pretty costly (40 ms) on my machine, so we keep it
around for reuse.
The advantage is that we can reliably know what all the aliases of a given unit
are. This means we can reliably load dropins under all names. This fixes #11972.
TEST-15-DROPIN: add test for details of unit aliasing
I adjusted the tests to pass. I don't think the behaviour makes much sense,
even if we ignore the issue with "lazy loading" of aliases. E.g. in the
last section, the fact that dropins for yup@.service and yup@3.service are
not loaded seems to be a plain old bug.
waitid(2) and the libc function signature calls this "exit status", and
uses "exit code" for something different. Let's stick to the same
nomenclature hence.
