Maciej - Thanks for opening a bug to track this.

I believe that I've fixed this bug. Unfortunately, the code was getting so ugly that I had to do 2 cleanup patches before I could cleanly solve the bug. I've just pushed the branch to:

git://git.kernel.org/pub/scm/linux/kernel/git/ecryptfs/ecryptfs-2.6.git irace

David - Let me know if you can pull the irace branch down and test out it. I'd appreciate it.

It will have to wait 'till tomorrow now, but I'll give it a whirl and report back.

Thanks
David

I can confirm that your patches seem to correct my issues. All looks fine through several kernel builds.

Cheers (and many thanks)
David

David - Thanks for testing that branch.

Linus just pulled the fixes in, so this should be fixed in 2.6.40-rc1.
