[PATCH 0/3] vmevent: Some fixes + a new event type

Hi all,

This small patch set fixes a bug in the vmevent core, plus makes the vmevent-test buildable w/o unneded SDL library.

Plus, we add a new 'cross' event type: the event will trigger whenever a value crosses a user-specified threshold. It works two-way, i.e. when a value crosses the threshold from a lesser values side to a greater values side, and vice versa.

We use the event type in an userspace low-memory killer: we get a notification when memory becomes low, so we start freeing memory by killing unneeded processes, and we get notification when memory hits the threshold from another side, so we know that we freed enough of memory.

The patches are against

Thanks!
