Linus Torvalds 200e9ef7ab vfs: split up name hashing in link_path_walk() into helper function ... The code in link_path_walk() that finds out the length and the hash of the next path component is some of the hottest code in the kernel. And I have a version of it that does things at the full width of the CPU wordsize at a time, but that means that we *really* want to split it up into a separate helper function. So this re-organizes the code a bit and splits the hashing part into a helper function called "hash_name()". It returns the length of the pathname component, while at the same time computing and writing the hash to the appropriate location. The code generation is slightly changed by this patch, but generally for the better - and the added abstraction actually makes the code easier to read too. And the new interface is well suited for replacing just the "hash_name()" function with alternative implementations.
