[linux-mm-cc] Re: Some testings using ccache pre-alpha 003 for i386

[Nitin Gupta]

Hi all,

I am currently planning home page update. This will take 1-2 days.
After this, I will carefully look at these tests and get a roadmap ready for
future development :)

One immediate thing to consider is improper handling of "real" low memory
conditions. It is surely more involving than: if (!ret) goto out; kind of
'error handling' as is done currently.

These tests will surely reveal many more issues.

Thanks Anderson for these tests! :-)

Cheers,
Nitin
