From 3e767e34bda1aa9e1d97a871a625558489ecaf56 Mon Sep 17 00:00:00 2001 From: Alexander Date: Mon, 17 Oct 2022 20:08:36 +0200 Subject: [PATCH] Linux compat: fix DECLARE_EVENT_CLASS() test when ZFS is built-in ZFS_LINUX_TRY_COMPILE_HEADER macro doesn't take CONFIG_ZFS=y into account. As a result, on several latest Linux versions, configure script marks DECLARE_EVENT_CLASS() available for non-GPL when ZFS is being built as a module, but marks it unavailable when ZFS is built-in. Follow the logic of the neighbor macros and adjust ZFS_LINUX_TRY_COMPILE_HEADER accordingly, so that it doesn't try to look for a .ko when ZFS is built-in.
