From 3ecdd2c69c4864526c63b8e55df22ad1a86f3c72 Mon Sep 17 00:00:00 2001 From: Andrew Clayton Date: Fri, 18 Nov 2022 23:42:44 +0000 Subject: Isolation: Rename NXT_HAVE_CLONE -> NXT_HAVE_LINUX_NS. Due to the need to replace our use of clone/__NR_clone on Linux with fork(2)/unshare(2) for enabling Linux namespaces(7) to keep the pthreads(7) API working. Let's rename NXT_HAVE_CLONE to NXT_HAVE_LINUX_NS, i.e name it after the feature, not how it's implemented, then in future if we change how we do namespaces again we don't have to rename this.
