distro specific kernels vs vanilla kernel and how to compare among each other

[devzero]

Hi !

does somebody know if there is a website or a project for giving comfortable and deeper insight into what`s specific to distro`s kernels and what`s their difference to vanilla kernel ?

i mean some way to have some transparancy to what different distro vendors add to vanilla kernel sources and thus turning it into their own specific version. 

some simple version of this could be a simple browseable archive like this:

if something like this doesn`t already exist - would it be useful to start such a project ?

There used to be such a page at kernelnewbies, but at some point it disappeared.

I agree it would be a useful resource.

I would also like to see something like this, as some work I'm doing on
working some funny networking (unfortunately IT department don't have
common sense) across multiple distros. Tracking the kernel patche
differences between the distros seems to be the hardest part (comparing
them to find what's needed for all distros to work).

besides a web-browseable directory structure with all the single broken-out patches (which are typically part of src.rpm or similar) , i assume it would be good to put those patched and unpatched kernel sources online via lxr ? ( http://lxr.linux.no/ )

As one of the persons who used to maintain that information on kernelnewbies
I agree.  It's just quite a bit of work and these days it's not always easy
to get at the vendor kernels anymore either.
