Commit 6a516acb2e moved the MemInfo type and
ReadMemInfo() function into the pkg/sysinfo package. In an attempt to assist
consumers of these to migrate to the new location, an alias was added.
Unfortunately, the side effect of this alias is that pkg/system now depends
on pkg/sysinfo, which means that consumers of this (such as docker/cli) now
get all (indirect) dependencies of that package as dependency, which includes
many dependencies that should only be needed for the daemon / runtime;
- github.com/cilium/ebpf
- github.com/containerd/cgroups
- github.com/coreos/go-systemd/v22
- github.com/godbus/dbus/v5
- github.com/moby/sys/mountinfo
- github.com/opencontainers/runtime-spec
This patch moves the MemInfo related code to its own package. As the previous move
was not yet part of a release, we're not adding new aliases in pkg/sysinfo.
