Re: [PATCH v7 1/4] spinlock: A new lockref structure for locklessupdate of refcount

[Linus Torvalds]

Just FYI: I've merged two preparatory patches in my tree for the whole
lockref thing. Instead of applying your four patches as-is during the
merge window, I ended up writing two patches that introduce the
concept and use it in the dentry code *without* introducing any of the
new semantics yet.

Waiman, I attributed the patches to you, even if they don't actually
look much like any of the patches you sent out. And because I was
trying very hard to make sure that no actual semantics changed, my
version doesn't have the dget_parent() lockless update code, for
example. I literally just did a search-and-replace of "->d_count" with
"->d_lockref.count" and then I fixed up a few things by hand (undid
one replacement in a comment, and used the helper functions where they
were semantically identical).

 You don't have to rewrite your patches if you don't want to, I'm
planning on cherry-picking the actual code changes during the merge
window.
