CONFIG_REISERFS_RAW (http://www.namesys.com/config.html)

[Marc-Christian Petersen]

Hi all,

can anyone tell me where I can find this code:


CONFIG_REISERFS_RAW
    Setting this to yes will enable a set of ioctls that provide raw
    interface to the ReiserFS tree, bypass the directories, and
    automatically remove aged files. This is an experimental feature
    designed for squid cache directories. See Documentation/filesystems/reiserfs_raw.txt
    This was designed specifically to use ReiserFS as a back-end for
    the Squid. The general idea is that it is possible to bypass all
    filesystem overhead and to directly address the ReiserFS internal
    tree. This is not in the stock kernels. 

?

Thanks.

ciao, Marc

You don't want to use it...

But if you do:

http://swelltech.com/pengies/joe/squidng.html

This page has the last versions of both the Squid and ReiserFS that have 
this feature.  It hasn't been supported in over two years, and it wasn't 
a trivial set of patches even then...I doubt you'd have much hope of 
getting either working in recent versions of Squid or kernel without 
significant help from both projects (probably paid help--this is deep 
code, and a lot of work to integrate).  It was a pretty darned fast 
Squid, though.

Perhaps also worth mentioning...Reiser4 has a plug-in interface that 
would make this sort of work easier.  You'd still need to do significant 
work in Squid, but it is also easier in new Squids.  (The devel Squid 3 
branch is becoming C++, and has a more clean and modular storage 
interface than even current Squids.)

The sponsor for the work did the usual dotcom number....

We would be happy to do more work if there was a sponsor....
