Mike, Here's a few fixes for OrangeFS.
Most important is to run getattr for size during a mmap page fault. I have also found a bug in d_revalidate. The test is backwards. However I haven't found a test that demonstrates that it is wrong, which makes me doubt that all the code here is completely optimal. The others are supposed to improve performance but appear to be below the noise floor.
