In some usages, e.g. virtio-balloon, a kernel module needs to know if page poisoning is in use. This patch exposes the page_poisoning_enabled function to kernel modules.

This patch adds support to walk through the free page blocks in the system and report them via a callback function. Some page blocks may leave the free list after zone->lock is released, so it is the caller's responsibility to either detect or prevent the use of such pages. One use example of this patch is to accelerate live migration by skipping the transfer of free pages reported from

...Asterisk receives the 1100Hz CNG tone from the sending modem. At that point, the call is dumped into t38modem which re-invites the TNT with the T.38 options, and the TNT usually sends a T.38 t30-ind of 0x00 (no-signal) or 0x3a (???), although I do occasionally see more promising messages like v29-7200-training or t30-data/hdlc-fcs-ok. Shortly thereafter, the dialing modem will give up and terminate the call. If I try dumping the same call into iaxmodem instead of t38modem, the call actually progresses further -- the real modem receives and decodes the HDLC CSI/DIS from iaxmodem, but th...
