4.2 scheduler

[Chris Torek]

The biggest slowdown in 4.2 was probably the long file names.
These slow down namei() quite a bit; and kernel profiles on our
machines have shown that namei() is by far the top competitor for
user CPU time of all the non-interrupt level code.

The fix is to install 4.3 as soon as it is out.
