As of Linux 5.3-rc5, there are 31205 [1] exported symbols in the kernel. That is a growth of roughly 1000 symbols since 4.17 (30206 [2]). There seems to be some consensus amongst kernel devs that the export surface is too large, and hard to reason about.This is good work. One solution for drastically reducing the effective export surface is to have CONFIG_TRIM_UNUSED_KSYMS=y. This is more extreme than symbol namespace, but might be worth mentioning nevertheless.
Oh that's amazing, I never noticed that feature. That is a nice thing, thanks for pointing it out. greg k-h
