dax: move DAX-related functions to a new header (c94c2acf) · Commits · 戴 / test

In order to handle the !CONFIG_TRANSPARENT_HUGEPAGES case, we need to return VM_FAULT_FALLBACK from the inlined dax_pmd_fault(), which is defined in linux/mm.h. Given that we don't want to include <linux/mm.h> in <linux/fs.h>, the easiest solution is to move the DAX-related functions to a new header, <linux/dax.h>. We could also have moved VM_FAULT_* definitions to a new header, or a different header that isn't quite such a boil-the-ocean header as <linux/mm.h>, but this felt like the best option.
