Subject: Re: [Linux Kernel Bug] WARNING in remove_vm_area

Hello,

Apologies for the oversight in my previous email. I neglected to
include the formatted report.

Please find the formatted report (formatted by syz-symbolize) attached
to this email. This should be easier to read and analyze.

Sorry for any inconvenience.
