After this patch, org-mode loads the most updated config. A minor issue that I have is that this patch creates config.el in my dotfiles directory, instead of ~/.emacs.d/config.el ,since ~/.emacs.d/
config.org is a symlink to ~/dotfiles/
config.org. The behaviour in org-9.1.5(emacs 26.3), was resolution of symlinks for just fetching the file attributes(file-modification-time). The below patch summarizes the changes that would keep the current version in line with current version in emacs release org-9.1.5(emacs 26.3).
