You can shake the kernel as much as you want, you wont make : - a TCP socket - a dentry - an inode - a file structure - eventpoll structures (assuming epoll use) - 2 dst per flow. In 1024 bytes of memory, and keep an efficient kernel to handle arbitrary number of sockets using the venerable and slow BSD socket api. I was objecting to the "crazy things like LWIP" comment from Josh, not to your patches in general. I actually took a look at them but stopped at patch 22 Adding ~1000 lines of code to save few KB was the point I gave up. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
