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@xxxxxxxxxx/#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!
