[lc-devel] Compressed Cache time !

[Nitin G. <nit...@gm...>]

Hi Rodrigo,

The exams are now nearly over and I can now work full time on
Compressed Cache :). Thanks for adding me as a developer in this
project!

I've just started looking at VMM code and your previous
implementation. Now, I am working on collecting all the things done up
to now and making up a general workflow for this work (I'll post it
very soon).

Also, I have very little experience working with CVS and it appears to
be a complex tool. So, it can take me some time to get working
smoothly with online repository. So, also learning CVS to get some
hang of it. Sorry, I can see here some trouble for you :).

While reading your code, I just noticed that you have also made
changes outside mm/ like in fs/inode.c, fs/smbfs/dir.c and some others
in fs/. Did the implementation required changes to other kernel parts
which had to do something with caches? I don't even know what is being
done but just thought it would be nightmare to maintain it if it
requires changes all over the kernel. Maybe, I haven't understood your
idea there. I think, compressed cache should be completely transparent
to rest to kernel subsystems.

Also, do you think we need to work out a way to actually store huge
pages in compressed cache. ? I currently only have a little intuitive
understanding of impact of compressed cache on other caches but I
think, after some initial development we will be able to take benefit
of many things 2.6 kernels offer.


Best Regards,

Nitin
