WebMar 7, 2024 · The config for 5.9 is about 10% more lines than 5.10. 5.9 has a lot of stuff compiled as modules. 5.10 doesn’t have that much enabled, but what it has is mostly compiled into the kernel. Just a few things (mostly within crypto have gone from built in (in 5.9) to modules (in 5.10). What might look most relevant is
