Linus Torvalds ae2a823643 dcache: move the DCACHE_OP_COMPARE case out of the __d_lookup_rcu loop 
__d_lookup_rcu() is one of the hottest functions in the kernel on
certain loads, and it is complicated by filesystems that might want to
have their own name compare function.

We can improve code generation by moving the test of DCACHE_OP_COMPARE
outside the loop, which makes the loop itself much simpler, at the cost
of some code duplication.  But both cases end up being simpler, and the
"native" direct case-sensitive compare particularly so.
