Subject[PATCH RESEND 0/4] hv_balloon: fixes for num_pages_onlined accounting and misc improvements
I just noticed that this series got lost; the initial submission was on
Nov, 8 but nothing happened after. Resending.

Original description:

While doing routing code review I noticed that commit 6df8d9aaf3af
("Drivers: hv: balloon: Correctly update onlined page count") introduced
an issue with num_pages_onlined accounting on memory offlining. Deeper look
showed that the accounting was always buggy. This is fixed in PATCH3.
PATCHes 1 and 2 are preparatory cleanups, PATCH4 adds a tracepoint to
post_status so it's now possible to see what's being sent to the host and
where the data comes from.

Vitaly Kuznetsov (4):
hv_balloon: fix printk loglevel
hv_balloon: simplify hv_online_page()/hv_page_online_one()
hv_balloon: fix bugs in num_pages_onlined accounting
hv_balloon: trace post_status
