From d01ad197ac3b50a99ea668697acefe12e73c5fea Mon Sep 17 00:00:00 2001 From: Ross Zwisler Date: Wed, 6 Sep 2017 16:18:47 -0700 Subject: dax: remove DAX code from page_cache_tree_insert() Now that we no longer insert struct page pointers in DAX radix trees we can remove the special casing for DAX in page_cache_tree_insert(). This also allows us to make dax_wake_mapping_entry_waiter() local to fs/dax.c, removing it from dax.h.
