Subject: [PATCH v2 0/4] Improve memory statistics for virtio balloon

Hi,

v1 -> v2:
- Add a new patch 'virtio_balloon: separate vm events into a function'
  to avoid any compiler warnings(unused stack variable on
  CONFIG_VM_EVENT_COUNTERS=n)
- Suggested by David, use a loop 'for (zid = 0; zid < MAX_NR_ZONES; zid++)'
  to obtain all the stall events.

RFC -> v1:
- several text changes: oom-kill -> oom-kills, SCAN_ASYNC -> ASYN_SCAN.
- move vm events codes into '#ifdef CONFIG_VM_EVENT_COUNTERS'

RFC version:
Link: https://lore.kernel.org/lkml/20240415084113.1203428-1-pizhenwei@bytedance.com/T/#m1898963b3c27a989b1123db475135c3ca687ca84

zhenwei pi (4):
  virtio_balloon: separate vm events into a function
  virtio_balloon: introduce oom-kill invocations
  virtio_balloon: introduce memory allocation stall counter
  virtio_balloon: introduce memory scan/reclaim info
