Hi, We want to propose a way to upgrade a kernel on a machine without restarting all the user-space services. This is to be done with CRIU project, but we need help from the kernel to preserve some data in memory while doing kexec. The key point of our implementation is leaving process memory in-place during reboot. This should eliminate most io operations the services would produce during initialization. To achieve this, we have implemented a pseudo file system that preserves its content during kexec. We propose saving CRIU dump files to this file system, kexec'ing and then restoring the processes in the newly booted kernel.
