Re: [PATCH v5 13/24] mm/process_vm_access: set FOLL_PIN via pin_user_pages_remote()

Convert process_vm_access to use the new pin_user_pages_remote() call, which sets FOLL_PIN. Setting FOLL_PIN is now required for code that requires tracking of pinned pages.

Also, release the pages via put_user_page*().

Also, rename "pages" to "pinned_pages", as this makes for easier reading of process_vm_rw_single_vec().
