Hello, Kernel Samepage Merging (KSM) [1] seems to be an interesting linux kernel feature and I wonder if I should expect it to work with podman. On my Fedora 35 [2], I tried to enable it (both by `echo 1 >/sys/kernel/mm/ksm/run`, and with `ksmtuned`) and started a few container instances _of the same_ (podman) image. But `/sys/kernel/mm/ksm/pages_shared` always shows 0. According to the KVM documention [3], it is supported there. But it seems that KSM support is an application opt-in (with `int madvise(addr, length, MADV_MERGEABLE)`). Hence my question is: Is KSM supported with podman? Kind regards, aanno [1] https://www.kernel.org/doc/Documentation/vm/ksm.txt [2] https://fedoraproject.org/wiki/Features/KSM [3] https://www.linux-kvm.org/page/KSM
