[PATCH 0/3] Dentry revalidation fixups

[Benjamin Coddington <bcodding@redhat.com>]

Trond's helped me out with my dentry revalidation woes.  The first two
patches fix races that may occur, and the third patch fixes a problem I've
tried to solve in the past where the client can decide not to revalidate a
dentry because we hold a delegation, but really it should be revalidated
because we cached that dentry before the delegation.  The most recent
attempt and discussion of that problem was here:

https://lore.kernel.org/linux-nfs/bcb5ffd399c4434730e6d100a5b7cae5e207244e.1580225161.git.bcodding@redhat.com/#t

That patch went to linux-next and should be dropped.  Anna, it looks like
you've already dropped it, but I just wanted to make a note of it.

Thanks for all the help, Trond!
