[resend PATCH v2 14/33] Revert "block: use DAX for partition table reads"

2017-04-17 Thread Dan Williams
commit d1a5f2b4d8a1 ("block: use DAX for partition table reads") was part of a stalled effort to allow dax mappings of block devices. Since then the device-dax mechanism has filled the role of dax-mapping static device ranges. Now that we are moving ->direct_access() from a block_device operation
