From: Trond Myklebust <trond.myklebust@xxxxxxxxxxxxxxx> The following patchset adds limited support for case insensitive filesystems to NFSv4. It adds the ability to detect such filesystems, and then turns off negative dentry caching. The reason is that we don't know which filenames in the dentry cache are actually case folded synonyms, so we need to ensure that we revalidate those negative dentries even for the case where our client created the file or directory.
