This PR enables CONFIG_USER_NS in the kernel configuration.
As part of our effort to support running unit tests for different gadgets of Inspektor Gadget on various kernel versions, we're using Vimto with the kernel images provided by ci-kernel (CONFIG_USER_NS enabled fork currently). However, Inspektor Gadget relies on specific runners to generate events that are later captured by different gadgets for testing. During this process, we retrieve the inode number and attempt to create a runner associated with UserNsID. Without CONFIG_USER_NS enabled, we are unable to create this runner as expected.
Would it be possible to enable CONFIG_USER_NS in the main ci-kernels repository to address this issue?
Thanks!
