From 2574c617362a0c67d15fa01e01cdbd0f6bcdbc93 Mon Sep 17 00:00:00 2001 From: Patrick Steinhardt Date: Wed, 19 Nov 2025 08:50:59 +0100 Subject: [PATCH] chdir-notify: add function to unregister listeners While we (obviously) have a way to register new listeners that get called whenever we chdir(3p), we don't have an equivalent that can be used to unregister such a listener again. Add one, as it will be required in a subsequent commit.
