A valid PTE is always treated as readable. There can be no valid PTE that is not readable. - LX_BLKPAG_OS_{READ,WRITE} are used only for debugging purposes, and has been superseded by LX_BLKPAG_AF and LX_BLKPAG_DBM. - Improve comment The need for reference/modify emulation has been eliminated, and access/permission faults have been reduced, however, there has been little change in overall performance.
