Help text

Map persistent memory, i.e. advertise it to the memory management sub-system. By default persistent memory does not support direct I/O, RDMA, or any other usage that requires a 'struct page' to mediate an I/O request. This driver allocates and initializes the infrastructure needed to support those use cases.
