Subject: Re: Inode Lock Scalability V7 (was V6)
Folks,
I just pushed a new version of this patchset which is pretty much a rebase on
2.6.36 out. I'm not going to post all the patches as not much changed - mostly
comments were changed. The changelog for the update is:
Version 7:
- rebase on 2.6.36
- iref() to inode->i_ref++ conversion in fs/nfs/write.c
- removed stray inode hash removal call from patches it didn't
belong in.
- cleaned up another stale remove_inode_hash comment.
- cleaned up more comments as reported by Christian Stroetmann
<stroetmann@...olinux.com>.
