Yes. This is because we haven't implemented a cleanup_module() yet in
order to release the kmem caches. Most of the work is already done:
see nfs_destroy_nfspagecache() et al. We just need the actual cleanup
function that calls them all. It's on my list.

This is surprising given that you're using synchronous writes, but it
is basically harmless. What kind of stress test was this though?
In any case the handling of file attribute updates has been changed in
the 2.3.99-pre4 series.

Cheers,
