    Hi, folks.
    I added my own system call (utterly simple one) to my Linux 2.6 source code.
    I worked well when I implemented it in the new file.
    I put the sys_mysyscall() function in the new file kernel/mysyscall.c
    and I modified the Makefile to compile this file, too.
    Of course I added one line in the entry.S and unistd.h
    I worked well...but,
    After I moved the function into the file kernel/sched.c , and removed my
    file
    kernel/mysyscall.c, It failed!
    The code was compiled well, but failed to link because it couldn't find the
    symbol "sys_mysyscall" in the entry.S !!
    How can I fix this problem??

    TIA
