From d9e5d31084b024734e64307521414ef0ae1d5333 Mon Sep 17 00:00:00 2001 From: Amir Goldstein Date: Tue, 12 Dec 2023 11:44:40 +0200 Subject: fsnotify: optionally pass access range in file permission hooks In preparation for pre-content permission events with file access range, move fsnotify_file_perm() hook out of security_file_permission() and into the callers. Callers that have the access range information call the new hook fsnotify_file_area_perm() with the access range.
