CFS made a bunch of fixes to it a few years ago, when it wasn't in either the 2.4 or 2.6 kernels. A few times in the intervening years there have been problems fixed, but nothing since then. The directory structure (or lack thereof) of the Lustre storage servers (OSTs) is such that they will always have tens to hundreds of thousands of files in each directory, so the code is definitely well-tested. We don't modify the htree code at all in either 2.6.9-RHEL or 2.6.12, only 2.6.5 SLES9 has a small patch for "." and ".." lookup.
