Emacs: how to disable 'file changed on disk' checking?

Question

How to disable Emacs from checking the buffer file was changed outside the editor?

Answer 1

I had annoyance with this because every time I switched branches in git, emacs thought all my files had changed.

Revbuffs helps you cope with the symptoms of this. It allows you to cause all your buffers to be reloaded.

You can also try (global-auto-revert-mode) which will automatically revert your files to what's on disk.
