Hi

2012/9/24 Alan Cox [off-list ref]:

flush_to_ldisc calls into the tty core code which sleeps. The rule is
that you may not call flush_to_ldisc except from a workqueue context.

If you break that rule then various bad things will occur (eg rx ->
flush_to_ldisc -> n_tty -> flow control -> tx -> deadlock) in a lot of
drivers.


Several of them are ones that shouldn't.

OK, I now understand what you mean with "pile that has needs to move
the other way"
I'll abandon this patch.

Thank you all for reviewing

Regards,
Ivo Sieben
