Indeed you are correct, never mind
Hum, so the only thing this config does is short circuit here:
static inline bool is_device_public_page(const struct page *page)
{
return IS_ENABLED(CONFIG_DEV_PAGEMAP_OPS) &&
IS_ENABLED(CONFIG_DEVICE_PUBLIC) &&
is_zone_device_page(page) &&
page->pgmap->type == MEMORY_DEVICE_PUBLIC;
}
Which is called all over the p...

dev_pagemap related cleanups v3
Hi Dan, Jérôme and Jason,
below is a series that cleans up the dev_pagemap interface so that
it is more easily usable, which removes the need to wrap it in hmm
and thus allowing to kill a lot of code
Note: this series is on top of Linux 5.2-rc5 and has some minor
conflicts with the hmm tree that are easy to resolve.
