[stgt] [PATCH] changes in iscsi login/text prototypes, structs

I guess so, if i understand what i did, and how i will go on from here,
if it compiles and supports few iscsi/tcp sessions with and without chap.

It's never guaranteed, you know. There is nothing in it that knowingly 
breaks things. There can be bugs, and the code should be tested,
but isn't it always the case?

Fine. Then let's make it happen :)

I did not meant the distributions at all. What is the process for making 
large or structural changes? I can work out it all by myself, making changes
in the whole way iscsi code works and be happy with it. You will be probably
less happy, and reluctant to even try such a thing. If i go small step at a
time, then each time merging will pose a risk of breaking a release.
So i propose opening a branch (say from 1.0.8), and merging the patches there 
after they are reviewed. We can ask all those guys who experienced data loss
with iser to try the branch once it has the minimal new code in it. 
Then when it is tested, and has all the lacking features, we merge it, 
and only then the distros enter the game.
Is it acceptable?
