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.
Best, -Costa

We will be glad to queue up the fix when it hits Linus's tree as well.
