[PATCH pynfs v2 00/25] nfs4.1: add some directory delegation testcases

[Jeff Layton <jlayton@kernel.org>]

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):
