Ross Zwisler 68202c9f0a libnvdimm, nd_blk: mask off reserved status bits ... The "NVDIMM Block Window Driver Writer's Guide": http://pmem.io/documents/NVDIMM_DriverWritersGuide-July-2016.pdf ...defines the layout of the block window status register. For the July 2016 version of the spec linked to above, this happens in Figure 4 on page 26. The only bits defined in this spec are bits 31, 5, 4, 2, 1 and 0. The rest of the bits in the status register are reserved, and there is a warning following the diagram that says: Note: The driver cannot assume the value of the RESERVED bits in the status register are zero. These reserved bits need to be masked off, and the driver must avoid checking the state of those bits. This change ensures that for hardware implementations that set these reserved bits in the status register, the driver won't incorrectly fail the block I/Os.
