Kernel PPP driver broken in 2.4.10-pre14

Kernel PPP driver broken in 2.4.10-pre14

[Martin Heiss]

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)

Hi!

Next time do not waste your time; check the mailing list beforehand...

That problem was found, fixed and now waiting on some very-very long
queue to be merged.
