+Subject: [PATCH] ext4: fix super block checksum incorrect after mount
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+commit 9b6641dd95a0c441b277dd72ba22fed8d61f76ad upstream.
+
+We got issue as follows:
+[home]# mount  /dev/sda  test
+EXT4-fs (sda): warning: mounting fs with errors, running e2fsck is recommended
+[home]# dmesg
+EXT4-fs (sda): warning: mounting fs with errors, running e2fsck is recommended
+EXT4-fs (sda): Errors on filesystem, clearing orphan list.
+EXT4-fs (sda): recovery complete
+EXT4-fs (sda): mounted filesystem with ordered data mode. Quota mode: none.
+[home]# debugfs /dev/sda
+debugfs 1.46.5 (30-Dec-2021)
+Checksum errors in superblock!  Retrying...
+
+Reason is ext4_orphan_cleanup will reset ‘s_last_orphan’ but not update
+super block checksum.
+
+To solve above issue, defer update super block checksum after
+ext4_orphan_cleanup.
