Re: 2.6.19 file content corruption on ext3

I was mistaken, I'm still having file corruption with rtorrent.

Hello,
I had filesystem data corruption with rtorrent with 2.6.19.
I tried recent git with Peter Zijlstra patch
http://lkml.org/lkml/2006/12/16/144 and it seems that the problem is
fixed.


oh crap, I'd forgotten that test_clear_page_dirty() now fiddles with the
ptes.

I'd be really surprised if this was all due to a race though. Is everyone
who has observed this problem running SMP and/or premptible kernels?

Peter, why isn't that proposed patch's cleaning of the pte racy against
do_wp_page()?
