Subjectabout get_zeroed_page() and page_address()
In the get_zeroed_page()function, address = page_address(page)
1)Does address point to a contiguous block of 4KB of physical memory? i.e.can I access the individual bytes by *address++?
2)How is page_address() function defined? I did a grep and found something like: #define page_address(page) ({ if (!(page)->virtual) BUG(); (page)->virtual; })? What's (page)->virtual?

Any help would be greatly appreciated.
