This looks like a page cache index issue - lookups as spinning probably because of a stale entry that isn't clearing up, and I think the KASAN report on XFS accessing an object owned byt he shmem_inode_cache is a bad folio returned by a lookup that is now (was?) owned by a shmem file and so mapping->host points at a shmem inode, not an XFS inode. -Dave.
