-Find out whether you will need iSCSI zero-copy optimization. Since it is valuable only with scst_user user space dev handlers, most likely, you don't need this feature. If you don't, skip the kernel download, patch, rebuild

-- Decide whether you want to start from a vanilla Linux kernel source tree
-or from the kernel source tree specific to your Linux distribution. Vanilla kernel sources can be downloaded from http://www.kernel.org/pub/linux/kernel/. Unzip the downloaded archive under /usr/src:
-
[root@proj ]# cd /usr/src
-[root@proj src ]# tar -xjf /usr/src/linux-3.11.8.tar.bz2

-[root@proj linux ]# grep -i highmem .config

- If you have built a 32-bit kernel on a system with more than 1GB of memory,
