That would be:
if (dirent.d_type == DT_UNKNOWN)
oserror("readdir returned unknown type");
Which suggests the backing filesystem didn't indicate file type of a dir entry
through readdir(). Is this from Ext3, or is it from XFS?

Start with the latest patches. Trim away anything that requires weird
security stuff.

You can't just backport cachefiles, unfortunately. The newer FS-Cache stuff
has a load of asynchronicity stuff in there that affects cachefiles too.
One problem you've got with RHEL-5 is that you need to add an extra address
operation, but that would violate the kABI:-/
