For some reason, your e-mails with the patch are available on the syzkaller-bugs google groups archive. For example: https://groups.google.com/g/syzkaller-bugs/c/NgC9hA3GX_Q/m/vVqsx8KTBQAJ But even though your messages appear to be cc'ed to linux-kernel, I'm not seeing your messages on lore.kernel.org's mail archives. (wWith apologies to Lewis Caroll) "Curiouser and curiouser...." This makes me worried that somehow some or all of your messages to linux-ext4@ or linux-kernel@ on this matter are somehow getting lost. We see syzkaller's reply to your messages, and anything that you've cc'ed to syzkaller-bugs@googlegroups.com is available archived on Google Groups. However, if there were any other messages that you have sent, they may have been unseed by anyone else. :-( If you could send a patch with a full description and the appropriate Fixes: and CC: stable tags, could you make sure that you explicitly Cc me, just in case something is funny going on with your e-mails to mailing lists at vger.kernel.org? Many thanks! - Ted
