50 # The pmemblk engine does IO to files in a DAX-mounted filesystem.
51 # The filesystem should be created on an NVDIMM (e.g /dev/pmem0)
52 # and then mounted with the '-o dax' option. Note that the engine
53 # accesses the underlying NVDIMM directly, bypassing the kernel block
54 # layer, so the usual filesystem/disk performance monitoring tools such
55 # as iostat will not provide useful data.
