[Lars Ingebrigtsen]

branch: master
commit 03124c42019401022e58ca9ebfa9b41735957ffb
Author: Lars Ingebrigtsen <larsi@gnus.org>
Commit: Lars Ingebrigtsen <larsi@gnus.org>

    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).
