So we don't \nneed a special condition here to handle DEVICE_PRIVATE differently.\n\nIn general, I like the way you handle mpfns as it keeps all the special \ncasing out of the drivers.\n\nRegards,\n

It returns the range we allocate for the pagemap from the\ndevice_private_pgmap_tree maple tree, representing \"device private address\nspace\".\n\nBut it's correct that means we don't need special handling here.\n\n> \n> In general, I like the way you handle mpfns as it keeps all the special \n> casing out of the drivers.\n\nYeah, it does turn out quite neat.\n\nThanks for review,\nJordan.\n\n>
