Variable: buffer-auto-revert-by-notification

buffer-auto-revert-by-notification is a buffer-local variable defined in files.el.gz.

Documentation

Whether a buffer can rely on notification in Auto-Revert mode.

If non-nil, monitoring changes to the directory of the current buffer is sufficient for knowing when that buffer needs to be updated in Auto Revert Mode. Such notification does not include changes to files in that directory, only to the directory itself.

This variable applies only to buffers where buffer-file-name(var)/buffer-file-name(fun) is nil; other buffers are tracked by their files.

Probably introduced at or before Emacs version 27.1.
