Comment 224 for bug 317781

Can someone point me toward documentation for "data=alloc_on_commit"?

I am getting 0 byte files after system freezes on Ubuntu 10.04.01 (amd64) with kernel version 2.6.32-25. Just want to understand how one uses alloc_on_commit and how it works before I use it, and I can't find any proper documentation for it, just a few brief mentions in articles and forum postings.

Thanks.
