2.4.13 kernel and ext3???

2.4.13 kernel and ext3???

[P.Agenbag]

Hi
I just installed RedHat 7.2 with the 2.4.7 kernel. Low and behold, when 
I tried to install the latest kernels, I see that there are many options 
in the RedHat 2.4.7 kernel that are not even in the 2.4.13 kernel! How 
does this work? Also, I see many (EXPERIMENTAL) greyd-out areas in the 
kernel as well as other greyd out areas which are not experimental, yet 
won't allow me to select it ( reiserfs for example ) .
How can I get reiserfs to compile into the kernel, and to satsify my 
curiosity, how do you enable the experimental options?

Does it mean that if there is a fairly large difference between the 
RedHat 2.4.7 and the stock one from kernel.org, that they are not really 
the same? ie, does anyone foresee any future problems with redhat adding 
all these extra features to their kernel and people who would like to 
upgrade to a newer version ( for one, I selected ext3 during install, 
yet, now trying to install 2.4.13, I must revert back to ext2...)

Thanks

Turn on first option "Prompt for development and/or incomplete
code/drivers" in the first configuration sub-menu "Code maturity level
options".

Indeed, but that's a good thing because people often want/need
more features or bugfixes than what's in the standard kernel.

ext3 has been in Alan's kernels for a while now, you can
always upgrade to a new -ac kernel and keep using ext3.

Also, the fact that ext3 isn't available in 2.4 -linus
doesn't sound like a good reason to not make this useful
feature available to the users of Linux distributions ;)

patches, patches more patches...

in the code maturity level options select:

Prompt for development and/or incomplete code/drivers

much of what's different are drivers that either haven't yet been accepted
into the tree or won't be accepted for various reasons...

you can add ext3 by either grabbing the andrew morton et al patch from...

http://www.uow.edu.au/~andrewm/linux/ext3/

or by appling one of the ac series patches from alan.

I suspect when you see a new development tree be created (shortly) that a
significant amount of code will migrate into that.

Moving back and forth between ext2 and ext3 works transparently,
 see the docs here:

Getting ext3 into the base kernel is a fairly high priority.
