I'm try this patch for migration issues and send comments. I have some may be offtopic question: Is that possible to export balloon function balloon_set_new_target to GPL modules (EXPORT_SYMBOL_GPL) ? This helps to kernel modules (not in kernel tree) to contol balloonin (for example autoballoon or something else) without needing to write so sysfs. (Writing files from kernel module is bad, this says Linux Kernel Faq). _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
