Subject: Fix .dir-local.el caching for symlinks
X-Git-Tag: emacs-29.0.90~1910^2~8
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=03124c42019401022e58ca9ebfa9b41735957ffb;p=emacs.git

Fix .dir-local.el caching for symlinks

* lisp/files.el (dir-locals-read-from-dir): We want the time stamp
of the actual file, not the time stamp of the symlink (if
.dir-locals.el is a symlink) (bug#46122).
