This patch set progresses my effort to improve concurrency of
directory operations and specifically to allow concurrent updates
in a given directory.

I only got about half the patches, but the ones I did get didn't raise
my hackles.

HOWEVER.

This is very much a "absolutely requires ACKs from Al" series. Al?

Yes, I'm looking forward to Al's thoughts

Also, because I only got about half the patches, and there's 53 of
them total, I'd really like to see a git branch for something like
this. It makes it easier to review for me, and I suspect it makes it
easier for some of the test robots too.

github.com/neilbrown/linux.git branch pdirops

But if you have only time for one patch, 52/53 is the one to look at.

Thanks,
NeilBrown

But again - this needs Al to look at it. Iirc he had some fundamental
concern with the last version - hopefully now fixed, but ...
