RE : RE : [Linux-decnet-user] X and Decnet Freeze

[BASSIR M. <Moh...@ax...>]

Ok, if i think well, it seems the same freeze problem appear on the 2.5. =
So it is not a good solution for me to increase the 2.4 version to 2.5 =
with all the patchs.

At this time i'm in locked state.=20
Could you tell me the Patrick patch which reduces the number of hangs a =
lot ?=20
Is it a patch to add to the last send by Patrick ?

can be used to query all patches applied to DECnet, whoever wrote them =
and might be the easier reference for you.

By all means feel free to produce patches for DECnet in 2.4 but I =
suspect it will be a long job since the two kernels are different enough =
that you won't just be able to copy & paste parts. Also beware that some =
behaviour has changed and that I'd rather not back port anything to 2.4 =
which will change DECnet from the users perspective unless it can be =
shown to be 100% backwards compatible.

When 2.6 proper comes out, I'll probably want to give up maintaining =
DECnet in 2.4. I think one stable version and one development version at =
a time are enough and there are times when I think that I'm not really =
giving them the attention that they deserve. I'm expecting things at =
work to calm down in a month or two and I hope to do some of the larger =
tasks I have on my todo list then,

Steve.
