Folks,

Get a question today. Thanks in advance.

As we know, vmalloc and other memory allocation/de-allocation will
change/update
the swapper_page_dir maintain by the kernel.

I am wondering when/how the kernel synchronzie the change to user level
processes' page
directory entries from the 768th to the 1023th.

Those entries get copied from swapper_page_dir when a user process get
forked/created. Does the kernel
frequently update this information every time when the swapper_page_dir get
changed?

Regards,

Mike
