When you compile linux kernel through make menuconfig , you get drowned with options. Suppose you are looking for specific option, but you dont know much about that option and hence you dont know under which category it will come. This happened for me when i knew ssb has to be disable through my google search but didnt know much about it so didnt know under which options it will come under. Then i found this interesting information.You can type a slash (/) to make a search for the option you are looking for and it will give many details about matching module. So when i did / and ssh it gave a list of all portions of menuconfig page where the word ssb apear. Pretty useful and neat trick.
