I added the patch, rebuilt and rebooted.  It will take some time
before I'll report back since the issue is so hard to reproduce.

FWIW I could trigger it reliably by running a bunch of directory traversal
programs simultaneously on the same directory.  I have a script that fires
up multiple mutts pointing to the Maildirs for the high traffic Linux lists.

Hmm, I wonder if we should request that this patch be backported to
-stable.  Darrick, what do you think?

Seems like an excellent idea.

Hi,

I see 4.7.1. was released, however before testing it in the changelog I can't see the inode.c commit with the checksum fix.
Is there another commit that would provide an equivalent fix, or is the fix not part of 4.7.1?

Best regards,
