[Xen-devel] page->tlbflush_timestamp

[李德新 <topcoder9@xxxxxxxxx>]

Hi,
      page->tlbflush_timestamp is used to filter and flush the TLB whenever type change of page happens. But why does xen flush TLB upon the type change? And we already know that guest kernel will flush the TLB in order to make the page table modifications take effect.
     
      Thanks!

Best regards,

Sam
