Ross Zwisler 15256f6cc4 dax: check for QUEUE_FLAG_DAX in bdev_dax_supported() ... Add an explicit check for QUEUE_FLAG_DAX to __bdev_dax_supported(). This is needed for DM configurations where the first element in the dm-linear or dm-stripe target supports DAX, but other elements do not. Without this check __bdev_dax_supported() will pass for such devices, letting a filesystem on that device mount with the DAX option.
