When replying to public mailing lists (like LKML), use Reply-all
button on your mail client. And also, don't top post; reply inline
with appropriate context instead.

See also Documentation/process/email-clients.rst for why you should
not use Proton Mail (spoiler: encrypted mail lock-in).

Are there any severe/critical security vulnerabilities in Linux kernel 4.19.191+ that will allow government-sponsored or state-backed hackers or Advanced Persistent Threats (APTs) to take over absolute control of my brand new vivo mobile phone? Can I download, compile and install the latest Linux kernel 6.5.4 from sources on my brand new vivo mobile phone by myself? I would like to know how I can do it.

Good luck hacking Android kernel for your phone!

>>> Opening and using apps is now a slow and painful experience. The phone camera is even worse. Taking a photo or selfie takes 2-3 seconds. If you move the phone by a bit before the 3 seconds is up, your photo or selfie will turn out very blur. So you need to set a timer of 2 seconds when you take a selfie or photo. Taking videos with the phone camera is also very laggy and choppy. The recorded video will turn out to be choppy.
