The second release candidate for Linux Kernel 7.0 (RC2) features an unusual focus on testing, BPF helpers, core scheduling tweaks, and networking fixes, with minimal changes to drivers. This lighter driver footprint reduces the risk of sudden incompatibilities, although users with older hardware or custom kernel modules should be cautious before updating. It's recommended to test the new kernel in a controlled environment before deploying it on critical systems, particularly due to changes in BPF JIT layout that could affect older CPUs. Overall, RC2 aims to maintain stability while improving the kernel's core functionality, making it suitable for users who are comfortable with kernel compilation and testing
