    SubjectKernel PPP driver broken in 2.4.10-pre14
    Date
    Hi,
    the linux kernel 2.4.10-pre14 ppp driver seems to be broken for me.
    In kernels <= 2.4.9 it used to work fine!

    When i try to insmod the "ppp_async" module it complains about "unresolved
    symbol tty_register_ldisc" and therefore refuses to load.

    After looking at the changes being introduced in 2.4.10-pre I was able to fix
    the problem:

    The problem is caused by the fact, that in 2.4.10-pre* the line
    EXPORT_SYMBOL(tty_register_ldisc);
    has been _removed_ from 'net/netsyms.c'

    after readding this line (i added the "EXPORT_SYMBOL(tty_register_ldisc);"
    right under the tty_register_ldisc declaration in "drivers/char/tty_io.c",
    but "net/netsyms.c" should work too) and recompiling everything now works
    fine for me. (ppp_async now loads correctly again)

    Therefore I recommend you to readd the
    EXPORT_SYMBOL(tty_register_ldisc);
    line whereever you consider it the right place (e.g. drivers/char/tty_io.c
    etc)
