From: Jan Kara Subject: [PATCH 03/18] DAX: move RADIX_DAX_ definitions to dax.c Date: Mon, 18 Apr 2016 23:35:26 +0200 Message-ID: <1461015341-20153-4-git-send-email-jack@suse.cz> References: <1461015341-20153-1-git-send-email-jack@suse.cz> Cc: linux-ext4@vger.kernel.org, linux-mm@kvack.org, Ross Zwisler , Dan Williams , linux-nvdimm@lists.01.org, Matthew Wilcox , NeilBrown , Jan Kara To: linux-fsdevel@vger.kernel.org Return-path: In-Reply-To: <1461015341-20153-1-git-send-email-jack@suse.cz> Sender: owner-linux-mm@kvack.org List-Id: linux-ext4.vger.kernel.org From: NeilBrown These don't belong in radix-tree.c any more than PAGECACHE_TAG_* do. Let's try to maintain the idea that radix-tree simply implements an abstract data type.
