Right now the code is required to keep the pmd_fault handler (which is always disabled though) compiling. Once that one is gone the DAX code in __xfs_get_blocks can be removed. In fact Ross sent a patch to do just that as part of his PMD fault rework. _______________________________________________ Linux-nvdimm mailing list [email protected] https://lists.01.org/mailman/listinfo/linux-nvdimm
