From 8cc3b1ccd930fe6971e1527f0c4f1bdc8cb56026 Mon Sep 17 00:00:00 2001 From: Amir Goldstein Date: Mon, 29 Nov 2021 22:15:37 +0200 Subject: fanotify: wire up FAN_RENAME event FAN_RENAME is the successor of FAN_MOVED_FROM and FAN_MOVED_TO and can be used to get the old and new parent+name information in a single event. FAN_MOVED_FROM and FAN_MOVED_TO are still supported for backward compatibility, but it makes little sense to use them together with FAN_RENAME in the same group. FAN_RENAME uses special info type records to report the old and new parent+name, so reporting only old and new parent id is less useful and was not implemented. Therefore, FAN_REANAME requires a group with flag FAN_REPORT_NAME.
