Subject: [PATCH 6.1 0/2] erofs: handle overlapped pclusters out of crafted images properly

Commit 9e2f9d34dd12 ("erofs: handle overlapped pclusters out of crafted
images properly") fixes CVE-2024-47736 [1] but brings another problem [2].
So commit 1a2180f6859c ("erofs: fix PSI memstall accounting") should be
backported too.
