5.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: J. Bruce Fields <bfields@xxxxxxxxxx>
[ Upstream commit 47fdb22dacae78f37701d82a94c16a014186d34e ]
I think this unusual use of struct compound_state could cause confusion.
It's not that much more complicated just to open-code this stateid
lookup.
The only change in behavior should be a different error return in the
case the copy is using a source stateid that is a revoked delegation,
but I doubt that matters.
