Another Substantial Improvement

Linus has just written a quick note about his pull on Nick Piggin's work on RCU lookup that he considered scary, but interesting and impressive one. Scary since it's some very core code, but he also likes it because it significantly improve the performance on his machine (he only conduct a small test with find).

I'm looking forward to see major performance improvements on Linux Kernel 2.6.38 which should be out around April
