Date: Mon, 31 Jan 2005 01:25:51 -0600 To: Andrew Morton <[email protected]> This patch series introduced a new pair of CONFIG_EMBEDDED options call CONFIG_BASE_FULL/CONFIG_BASE_SMALL. Disabling CONFIG_BASE_FULL sets the boolean CONFIG_BASE_SMALL to 1 and it is used to shrink a number of core data structures. The space savings for the current batch is around 14k. - For example , look at the file "Linux/include/linux/udp.h" http://lxr.free-electrons.com/source/include/linux/udp.h #define UDP_HTABLE_SIZE_MIN (CONFIG_BASE_SMALL ? 128 : 256) > -- > regards, > > Mulyadi Santosa > Freelance Linux trainer and consultant > > blog: the-hydra.blogspot.com > training: mulyaditraining.blogspot.com > -- > To unsubscribe from this list: send the line "unsubscribe linux-kernel" in > the body of a message to [email protected] > More majordomo info at http://vger.kernel.org/majordomo-info.html > Please read the FAQ at http://www.tux.org/lkml/ > -- Best Regards Lin -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to [email protected] Please read the FAQ at http://kernelnewbies.org/FAQ
