Re: [Xen-devel] Balloon driver and oom-killer

[tgh <wwwwww4187@xxxxxxxxxxx>]

hi
I have used balloon driver in xen,and I am confused about the  meaning  
of "Improve interaction between balloon driver and page
allocator to avoid memory crunch."in the roadmap,what does it mean exactly? 
does it mean to improve the performance of the balloon, or to add some other 
functionality ,or to make the guestos's memory size adapted automatically,or 
something else?
 
Thanks in advance
