xenpaging: munmap all pages after page-in
|
||
|
|
|
||
|
|
Do munmap() on all mapped pages, not just the first one. Without this
|
||
|
|
change the gfns backing the remaining pages can not be paged out again
|
||
|
|
because the page count does not go down to 1. This change was missing
|
||
|
|
from changeset 23827:d1d6abc1db20.
