[PATCH v2 0/6] selftests/resctrl: Add dynamic linked list management for IMC counters

[Yifan Wu]

Hi all,

This patch series adds dynamic linked list management for the IMC
counters, which can work based on the actual number of counters instead of
an upper limit, without the need for array out-of-bounds access check.

This patch series is based on the Reinette's patch series aimed at fixing
the resctrl test and can be found at:
https://lore.kernel.org/lkml/cover.1775266384.git.reinette.chatre@xxxxxxxxx/

changelog:
1. Fixed the code style and variable naming.
2. The initialization and cleanup of the linked list are integrated in patch 1.
3. The use of arrays is refactored to linked list split in the remaining patches.
4. The IMC count and global variable imcs are removed.
For more details, see the commit message.

v1 can be found at:
