[PATCH pynfs v3 00/26] nfs4.1: add some directory delegation testcases

[Jeff Layton <jlayton@kernel.org>]

Long delay since v2, but the CB_NOTIFY patches only recently got merged
into Chuck's nfsd-testing branch. They're currently slated to make v7.3.
This version of the series fixes some potential state leaks that Scott
pointed out, and adds a patch to make the output a bit less chatty with
normal settings.

Original cover letter follows:

---------------------8<-------------------

This patchset adds some new testcases for directory delegations.

DIRDELEG1-7 should pass on current mainline kernels, with recall-only
support. The rest require CB_NOTIFY support. If the server doesn't
offer notifications, then the tests pass_warn (so there should be no
failures in those cases):
