4e83ac4029 Revert "TEST-55-OOMD: workaround for kernel regression in 6.12-rcX"
This reverts commit 88bbf187a9.

The kernel regression has been hopefully fixed by
c650812419
which is included in 6.12-rc4.
Let's drop the workaround.

88bbf187a9 TEST-55-OOMD: workaround for kernel regression in 6.12-rcX
This ignore failures when running on kernel-6.12-rcX, which has a
regression in the kernel scheduler that breaks PSI.

From https://github.com/systemd/systemd/issues/32730#issuecomment-2415312260
> There is a known scheduler bug in 6.12 that breaks psi. It leaks
> "running tasks" counts, which matches your symptoms of seeing partial
> pressure only.
>
> Do you see "inconsistent task state" warnings in dmesg | grep psi?
>
> A fix is queued in the scheduler tree, should be sent to Linus shortly:
> https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/commit/?id=c6508124193d42bbc3224571eb75bfa4c1821fbb

Workaround for #32730.

63d4c4271c cgroup: Add ManagedOOMMemoryPressureDurationSec= override setting for units
This will allow units (scopes/slices/services) to override the default
systemd-oomd setting DefaultMemoryPressureDurationSec=.

The semantics of ManagedOOMMemoryPressureDurationSec= are:
- If >= 1 second, overrides DefaultMemoryPressureDurationSec= from oomd.conf
- If is empty, uses DefaultMemoryPressureDurationSec= from oomd.conf
- Ignored if ManagedOOMMemoryPressure= is not "kill"
- Disallowed if < 1 second

Note the corresponding dbus property is DefaultMemoryPressureDurationUSec
which is in microseconds. This is consistent with other time-based
dbus properties.

Then, sleep becomes not necessary anymore. This greatly improve performance.

665882f8f3 TEST-55-OOMD: check slice more in detail
system and user slice has same name, hence we need to check full path.

6bba058076 TEST-55-OOMD: split into small testcases
Then, we can run each small test cases separately.

23fb9b63cd TEST-55-OOMD: check global config earlier
'Default Memory Pressure Duration' field in oomctl, which can be configured
with DefaultMemoryPressureDurationSec= in oomd.conf, is a global config.
Let's check it earlier.

This also drops unnecessary cleanup at the beginning.

1473836a1e TEST-55-OOMD: set ManagedOOMMemoryPressure= and friends in a drop-in config
Fedora and friends has a drop-in config for the settings in
/usr/lib/systemd/user/slice.d/ . Hence, settings in the main .slice may be
overridden. Let's set below in a drop-in with higher decimal prefix.

Also, rename override.conf -> 99-managed-oom-preference.conf for the same reason.

3e3a15c06e TEST-55-OOMD: Switch to stress-ng
stress-ng is available in OpenSUSE and in CentOS Stream without needing
EPEL so let's switch to it instead of stress.

7a321b5a21 test: Rename testsuite-XX units to match test name
Having these named differently than the test itself mostly creates
unecessary confusion and makes writing logic against the tests harder
so let's rename the testsuite-xx units and scripts to just use the
test name itself.
