UKSM breaking pages getting read access from KVM VMs #67
Description
Configurations used for UKSM used:
UKSM configured with 2 ladders.
cpu_ratios: MAX/2 MAX/2
eval_intervals: 0 0
We observed merged pages breaking on simple reads while the reads originate from within VMs. It should ideally break on writes to the merged pages.
But things do work normally for applications running on bare metal machine.
