On the http://kernelnewbies.org/projects/ there is second item about some functions that useless(or may be not?). For example: In kernel source file "include/asm-i386/smp.h" there is a string with prototype of function extern void smp_invalidate_rcv(void); and no one file does not have referense to this function and it does not have definition of it. May i delete it string from source? Look at this http://lxr.linux.no/ident?v=2.5.38;i= And may be we have some other functions in kernel source that simillar to smp_invalidate_rcv. And most important question for me: would it be usefull if I'll wrote script that delete all such prototypes? mailto:cubic@wr.miee.ru -- Kernelnewbies: Help each other learn about the Linux kernel.
