Linux is widely used in embedded systems which always have storage limitation and hence requires size optimization. In order to reduce the kernel size, based on the previous work of the “Section Garbage Collection Patchset”, This paper focuses on details its principle, presents some new ideas, documents the porting steps, reports the testing results on the top 4 popular architectures: ARM, MIPS, PowerPC, X86 and at last proposes future works which may enhance or derive from this patchset.
