This way we don't need to repeat the argument twice.
I didn't replace all instances. I think it's better to leave out:
- asserts
- comparisons like x & y == x, which are mathematically equivalent, but
here we aren't checking if flags are set, but if the argument fits in the
flags.
Also, allow run-cocinnelle.sh to be started from any directory.
Unfortunately set -x does not work nicely anymore, because the list is
too verbose. Replace it by an echo line.
Previously, we'd not care about failures that were seen earlier and
remain in "exited" state. This could be triggered if the main process of
a service failed while ExecStartPost= was still running, as in that case
we'd not immediately act on the main process failure because we needed
to wait for ExecStartPost= to finish, before acting on it.

Let's show a message at the time of logout i.e. entering the "closing"
state, not just e.g. once the user closes `tmux` and the session can be
removed completely. (At least when KillUserProcesses=no applies. My
thinking was we can spare the log noise if we're killing the processes
anyway).
These are two independent events. I think the logout event is quite
significant in the session lifecycle. It will be easier for a user who
does not know logind details to understand why "Removed session" doesn't
appear at logout time, if we have a specific message we can show at this
time :).
Tested using tmux and KillUserProcesses=no. I can also confirm the extra
message doesn't show when using KillUserProcesses=yes. Maybe it looks a
bit mysterious when you use KillOnlyUsers= / KillExcludeUsers=, but
hopefully not alarmingly so.
I was looking at systemd-logind messages on my system, because I can
reproduce two separate problems with Gnome on Fedora 28 where
sessions are unexpectedly in state "closing". (One where a GUI session
limps along in a degraded state[1], and another where spice-vdagent is left
alive after logout, keeping the session around[2]). It logged when
sessions were created and removed, but it didn't log when the session
entered the "closing" state.

The function is similar to path_kill_slashes() but also removes
initial './', trailing '/.', and '/./' in the path.
When the second argument of path_simplify() is false, then it
behaves as the same as path_kill_slashes(). Hence, this also
replaces path_kill_slashes() with path_simplify().
This "netdevsim" as implied by the name is a tool for network developers and is a simulator.
This simulated networking device is used for testing various networking APIs and at this time
is particularly focused on testing hardware offloading related interfaces.
We don't need a temporary variable when parsing just one number, because
our parsing functions do not touch the output variable on error.
TAKE_PTR is more expressive than 'n = NULL'.
First, ellipsize() and ellipsize_mem() should not read past the input
buffer. Those functions take an explicit length for the input data, so they
should not assume that the buffer is terminated by a nul.
Second, ellipsization was off in various cases where wide on multi-byte
characters were used.
We had some basic test for ellipsize(), but apparently it wasn't enough to
catch more serious cases.
Should fix https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=8686.
Add accelerometer orientation quirk for the Onda V891w tablet, this
does a partial match on the BIOS version because the other strings are
somewhat generic.
The BIOS match is done for both the W89* and D89* BIOS versions which are
for the Windows only and Dual boot versions respectively.
* it fails with gcc8 when -O1 or -Os is used (and -ftree-vrp which is added by -O2 and higher isn't used)

[zj: change 'char' to 'signed char']
sparc sets the carry bit when a syscall fails. Use this information to
set errno and return -1 as appropriate.
The added test case calls raw_clone() with flags known to be invalid
according to the clone(2) manpage.
We already do that in get_process_cmdline(), which is very similar in
behaviour otherwise. Hence, let's be safe and also filter them in
get_process_comm(). Let's try to retain as much information as we can
though and escape rather than suppress unprintable characters. Let's not
increase comm names beyond the kernel limit on such names however.
Also see discussion about this here:
https://marc.info/?l=linux-api&m=152649570404881&w=2
For short buffer sizes cellescape() was a bit wasteful, as it might
suffice to to drop a single character to find enough place for the full
four byte ellipsis, if that one character was a four character escape.
With this rework we'll guarantee to drop the minimum number of
characters from the end to fit in the ellipsis.
If the buffers we write to are large this doesn't matter much. However,
if they are short (as they are when talking about the process comm
field) then it starts to matter that we put as much information as we
can in the space we get.
This adds a flags parameter to unit_notify() which can be used to pass
additional notification information to the function. We the make the old
reload_failure boolean parameter one of these flags, and then add a new
flag that let's unit_notify() if we are configured to restart the
service.
Note that this adjusts behaviour of systemd to match what the docs say.

'systemctl disable --runtime' would disable a unit, but only if it was enabled
with '--runtime', and silently do nothing if the unit was enabled persistently.
And similarly 'systemctl disable' would do nothing if the unit was enabled in
/run. This just doesn't seem useful.
This pathch changes enable/disable and mask/unmask to be asymmetrical. enable
and mask create symlinks in /etc or /run, depending on whether --runtime was
specified. disable and unmask remove symlinks from both locations. --runtime
cannot be specified for the disable and unmask verbs.
The advantage is that 'disable' now means that the unit is disabled, period.
And similarly for 'unmask', all masks are removed.
Similarly for preset and preset-all, they now cannot be called with --runtime,
and are asymmetrical: when they enable a unit, symlinks are created in /etc.
When they disable a unit, all symlinks are nuked.
