Sorry, I put too much in the subject. I received e-mail this morning (Pacific Standard Time) that ext4-fix-superblock-checksum-calculation-race.patch had been incorporated into various stable branches. Yesterday, I received an e-mail from Hillf Danton (hdanton@sina.com) that syzbot had found a bug in the patch. Hillf Danton (hdanton@sina.com) has made a patch for the patch and it is being reviewed.
