[PATCH v3 0/3] make unused huge shrinker memcg aware

[Qi Zheng <qi.zheng@linux.dev>]

From: Qi Zheng <zhengqi.arch@bytedance.com>

Changes in v3:
 - add a fix patch to fix missed removal of super_fs_objects_eligible()
 - move the original shrinklist addition logic after all checks are completed,
   and split it into a separate patch. (suggested by Baolin)
 - simplify the shmem_unused_huge_requeue() (suggested by Baolin)
 - keep the move_back label in shmem_unused_huge_shrink() (suggested by Baolin)
 - rebase onto the next-20260731

Changes in v2:
 - temporarily add the dependent patch from Usama to the series for review
   convenience
 - remove shrinklist_scan and shrinklist_isolated from struct shmem_inode_info,
   and re-implement the logic by resuing the same info->shrinklist
   (suggested by Baolin)
 - add more comments (suggested by Andrew)
 - fix missing initialization of info->shrinklist_memcg (pointed by sashiko)
 - rebase onto the next-20260717
