+Subject: [PATCH 06/14] clone-internal.c: make clone3 syscall optional
+
+We're disabling clone3 for now _CONDITIONALLY_ (not by default) to allow
+compatibility with applications using older Electron.
+
+Use -DGENTOO_USE_CLONE3 to enable clone3 for now. In future, we will
+revert back to always using clone3.
+
+This was impacting e.g. Discord and Skype. This patch stops glibc from using
+clone3 internally (which is the only real use of it) and falls back to the old
+behaviour.
+
+Specifically, we want https://github.com/electron/electron/pull/31091
+to work its way downstream to various Electron applications.
+
+https://bugs.gentoo.org/819045
+https://bugs.gentoo.org/827386
+
+https://git.launchpad.net/~ubuntu-core-dev/ubuntu/+source/glibc/plain/debian/patches/ubuntu/disable-clone3.patch
+
+This is the same as the patch that was considered but ultimately rejected
+for 2.34 because Docker got sorted out in time:
+https://patchwork.ozlabs.org/project/glibc/patch/87eebkf8ph.fsf@oldenburg.str.redhat.com/.
