ftape and kernel 2.4 problem

ftape and kernel 2.4 problem

[Friedrich Lobenstock]

Hi!

As the linux-ftape mailing list is gone I'm asking you guys.

Can someone tell me how to adapt the ftape driver that I can use it
under kernel 2.4.x (x >= 5)? I'm not that into kernel hacking that
I know what changed from 2.2.x to 2.4.x. Below is the output of make.

BTW why wasn't the newer ftape driver ported to 2.4 but the stone age
ftape driver is still in 2.4?

PS: Please CC me because I'm not on linux-kernel.

Here's a patch I wrote to allow ftape to compile against 2.4.something.
It still works with 2.4.5.  I'm not sure if it works entirely (it seems
to), but it compiles and seems to work.  Enjoy!

I really do enjoy it despite compiling gives me a lot of warnings :)

Alan, how could we get the current in kernel ftape driver updated?
What needs to be done?

Someone needs to do it. To be honest the last ftape contribution I can find
is back in 2.3.30 or so and was some fixes to make it compile which were done
I think by someone without the hardware.

If you are actually using ftape you are I suspect the most qualified volunteer
for doing something about it I've seen for two years 8)

Hi Alan!

Sure, but what I wanted to know are there some documents that describe
the changes between 2.2 and 2.4? And how would you accept patches?

For sure I could only make it work - maybe with help by Steven
Walter - and then provide a patch for the whole thing. I know you and
Linus only want small patches. I think this will only relate to the
ftape drive, so I ask would the aformentioned big patch do? Or how'd
we split it up?

Maybe you could take a quick look at the latest state of the
driver (dont forget to count the small patch of Steven Walter)
and tell me what you think about the whole thing.
