    Patch in this message
    Subject9P compile fix
    With 9P but no 9P debug options, this error occurs:
    CC [M] fs/9p/v9fs.o
    fs/9p/v9fs.c: In function 'v9fs_parse_options':
    fs/9p/v9fs.c:134: error: 'p9_debug_level' undeclared (first use in this function)

    The following patch moves the definition of p9_debug_level out of #ifdef
    and seems to fix the compilation.
