[PATCH RFC] virtio_balloon: conservative balloon page shrinking

We could make it extendable:
#define BALLOON_SHRINKER_AFTER_PAGE_CACHE (1 << 0)
#define BALLOON_SHRINKER_AFTER_KVM_MMU_CACHE (1 << 1)
...
uint64_t conservative_shrinker;
if ((conservative_shrinker | BALLOON_SHRINKER_AFTER_PAGE_CACHE) && global_node_page_state(NR_FILE_PAGES))
return 0;
For now, we probably only need BALLOON_SHRINKER_AFTER_PAGE_CACHE.
Best,

[PATCH RFC] virtio_balloon: conservative balloon page shrinking
There are cases that users want to shrink balloon pages after the
pagecache depleted. The conservative_shrinker lets the shrinker
shrink balloon pages when all the pagecache has been reclaimed.
