Hi Martin, I shouldn't have been so pesemistic. I did indeed get a reply. Several in fact. http://lkml.org/lkml/2004/12/15/299 In a nutshell: 1. This patch wasn't put into 2.4.28 because it was quite intrusive and came out to late in the 2.4.28 cycle 2. It is planed for inclusion (in 2.4.29 I assume) 3. There are some updates to the patch both available and pending, I will make sure we get those, but broadly speaking the patch is unchanged. Actually, I notice that one of the uptades will most likely introduce a futher ABI change by adding "struct semaphore termios_sem;" to strut tty_struct. It would be good to get that in if we are going to increment the so number. http://lkml.org/lkml/2004/11/7/106 -- Horms
