move_pages() flush TLB once or multiple times?

909 Views

Hi,

I'm currently using move_pages() API which is from libnuma librray(http://man7.org/linux/man-pages/man2/move_pages.2.html). According to the description on the webpage, we can move multiple pages at one time. So if I use "move_pages" to move multiple pages, will system flush TLB once or system flush TLB every time for every page mapping update? Thanks.
