Allow me to be mildly pedantic (sorry :) One thing I'd like to highlight here is that remap_pfn_range() is, in the long run, deprecated.
mmap_prepare callbacks will indicate a PFN remap mmap_action, which will do the heavy lifting (see [0]). So perhaps worth referring to 'PFN remapping' or something? (Since we already have mmap_prepare() in use, it's also kinda inaccurate to say remap_pfn_range() :) [0]: https://www.kernel.org/doc/html/next/filesystems/mmap_prepare.html Sorry, this is pretty nitpicky :) Cheers, Lorenzo
