 xattr_nid is the same to its i_ino. dump.f2fs -i 3 chaseyu.img.raw i_xattr_nid [0x 3 : 3] So that, during
 mknod in the corrupted directory, it tries to get and lock inode page twice, result in deadlock. -

 f2fs_acl_create(dir,..) - __f2fs_get_acl - f2fs_getxattr - lookup_all_xattrs - __get_node_page --- try to
 lock dir's inode page In order to fix this, let's add sanity check on ino and xnid. (CVE-2025-38347)
