There are still stubs need to be tracked, like file mount code, memory management, but it can be improved later I think. commit edc9109d6d1a36f691872549762f954783a9a628 Author: Hajime Tazaki <tazaki@....wide.ad.jp> Date: Tue Mar 31 22:32:21 2015 +0900 lib: reduce glue codes (stubs) arch/lib/Makefile | 22 ++-- arch/lib/capability.c | 47 +++++++ arch/lib/cred.c | 16 --- arch/lib/dcache.c | 93 -------------- arch/lib/filemap.c | 5 + arch/lib/fs.c | 239 ++---------------------------------- arch/lib/glue.c | 75 ++--------- arch/lib/include/asm/Kbuild | 2 + arch/lib/include/asm/atomic.h | 5 +- arch/lib/include/asm/thread_info.h | 1 + arch/lib/inode.c | 146 ---------------------- arch/lib/lib.c | 5 + arch/lib/proc.c | 130 -------------------- arch/lib/sched.c | 41 +++++++ arch/lib/security.c | 45 ------- arch/lib/seq.c | 122 ------------------ arch/lib/slab.c | 3 + arch/lib/softirq.c | 4 + arch/lib/splice.c | 20 --- arch/lib/super.c | 210 ------------------------------- arch/lib/sysctl.c | 15 --- arch/lib/time.c | 5 - 22 files changed, 142 insertions(+), 1109 deletions(-) (full modification on this commit) https://github.com/libos-nuse/net-next-nuse/commit/edc9109d6d1a36f691872549762f954783a9a628 I still have a couple of comments, which I haven't addressed with the code (below). will work on too. * build system (Makefile) - parallel build issue - cross-build issue - missing dependency detection * code location - under arch/ or tools/ -- Hajime -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
