From 8b8c7d6148bc1bab3cf88cac49038a05db7dd938 Mon Sep 17 00:00:00 2001
From: Jan Kara <jack@suse.cz>
Date: Mon, 21 Sep 2020 11:33:23 +0200
Subject: [PATCH] dax: Fix compilation for CONFIG_DAX && !CONFIG_FS_DAX
dax_supported() is defined whenever CONFIG_DAX is enabled. So dummy
implementation should be defined only in !CONFIG_DAX case, not in
!CONFIG_FS_DAX case.
Fixes: e2ec51282545 ("dm: Call proper helper to determine dax support")
Cc: <stable@vger.kernel.org>
