Description: File system based Direct Access (DAX) support

More info: Direct Access (DAX) can be used on memory-backed block devices. If the block device supports DAX and the filesystem supports DAX, then you can avoid using the pagecache to buffer I/Os. Turning on this option will compile in support for DAX. For a DAX device to support file system access it needs to have struct pages. For the nfit based NVDIMMs this can be enabled using the ndctl utility: # ndctl create-namespace --force --reconfig=namespace0.0 \ --mode=fsdax --map=mem See the 'create-namespace' man page for details on the overhead of --map=mem: https://docs.pmem.io/ndctl-user-guide/ndctl-man-pages/ndctl-create-namespace
