[Pkg-iscsi-maintainers] Bug#581200: iscsitarget-source applies kernel compatibility patches the wrong way

[Markus Schuster]

Source: iscsitarget
Version: 1.4.20.1-1

Hello, 

I've "backported" iscsitarget to lenny (just used the Debian sources to 
produce binary packages) and want to use lennys 2.6.26 kernel. In general 
upstream iscsitarget works with this kernel just fine, but debian/rules for 
iscsitarget-source does the following:

> kdist_config: prep-deb-files
> # ... additional kernel specific things to configure...
>         test -f patches/compat-$(KERN_VER).patch && patch -p1 <
> patches/compat-$(KERN_VER).patch

The test && patch construct is not fully correct, as you have to apply ALL 
compatibility patches between the desired target version and the version, 
iscsitargt compiles with without patch. 
For example to be able to produce a working kernel module for 2.6.26 you have 
to apply the following patches:

compat-2.6.32.patch
compat-2.6.31.patch
compat-2.6.30.patch
compat-2.6.29.patch
compat-2.6.28.patch
compat-2.6.25-2.6.27.patch

So some sort of loop would be needed...
