Applying with these fixes on my side:
- put 5/5 "ms/eventfs: Initialize ei->children and ei->list in
  init_ei()" in front of this patch.

Why: at this patch eventfs_create_events_dir() can still reach
cleanup_ei() with the list heads zeroed by kzalloc(), when
tracefs_get_inode() fails, and this WARN fires there.

Your answer to Sashiko holds for the SRCU leak, but not for the WARN:
6.12.y took the init_ei() fix (c480f8af173d, v6.12.109) before
1b95382da85c, so it never had that window. 5/5 moves in front of this
patch without any change, the final tree stays the same.
