bug#42271: 27.0.91; Variable global-auto-revert-ignore-modes not working

 The variable global-auto-revert-ignore-modes is not working anymore (it
was working with Emacs 26.3). I've fixed the bug by removing the apostrophe
character of the
following line (file: autorevert.el, function:
auto-revert--global-add-current-buffer):

  (not (memq 'major-mode global-auto-revert-ignore-modes))


Steps to reproduce:

(progn
  (require 'autorevert)
  (setq global-auto-revert-ignore-modes (list 'Buffer-menu-mode))
  (setq global-auto-revert-non-file-buffers t)
  (global-auto-revert-mode t)
  (list-buffers))

bug#42271: 27.0.91; Variable global-auto-revert-ignore-modes not working

[Mattias Engdegård]

Thank you! It's my mistake and I'm very sorry about it.

Eli, this is a regression introduced in Emacs 27 and the fix amounts to the removal of a single quote. Can we do it on emacs-27?
