Re: Vnode API change: add global vnode cache
Sorry to disturb you.
But I have small comment about subject.
I think it is unnecessary overload involve mount point in lookup for global
You save few bytes for hashhead for every mount point, but loose effectively
Every lookup has one more compare for mp, and your hashtable will be more
In any case have hashhead and hashlock for every mount point is more flexible
"struct mount" is a good place for this.
