Character sequences starting with `\` are interpreted by python as
escaped Unicode characters. However, they have other meaning in
regular expressions (e.g: "\d").
It seems Python >= 3.12 starts emitting a SyntaxWarning when these
escaped sequences are not recognized as valid Unicode characters.

This makes pids.events:max affine to pids.max limit.
How are the new events supposed to be useful?
- pids.events.local:max
- tells that cgroup's limit is hit (too tight?)
- pids.events:*
- "only" directs top-down search to cgroups of interest
Changes from v3
(https://lore.kernel.org/r/20240
Hierarchical counting of events is not practical for watching when a
particular pids.max is being hit. Therefore introduce .local flavor of
events file (akin to memory controller) that collects only events
relevant to given cgroup.
The file is only added to the default hierarchy.

Currently, when pids.max limit is breached in the hierarchy, the event
is counted and reported in the cgroup where the forking task resides.
This decouples the limit and the notification caused by the limit making
it hard to detect when the actual limit was effected.

Fix the warnings by initializing and marking the variable as unused.
I've caught the warnings by using clang.

memory between the SBI implementati
