[Bug 1109908] regression: extreme page allocation stalls since upgrading from SLES12 / 42.3 kernel

a 2nd note - i'm able to trigger stalls of kvm processes via:

How long stalls in that case?

echo 1 >/proc/sys/vm/compact_memory is this expected?

Some disruption would be expected, as manually invoked compaction is much more heavyweight than the usual one. But depends on how long the echo takes to complete, and how long are the associated stalls. -- You are receiving this mail because: You are on the CC list for the bug.
