Subject: [PATCH 1/1] NFSv4.2: fix COPY attrs in presence of delegated timestamps
Date: Fri, 27 Mar 2026 12:57:57 -0400 [thread overview]
Message-ID: <20260327165757.28948-1-okorniev@redhat.com> (raw)
A similar to generic/407 test can be done with a COPY operation
instead of CLONE (reflink). And it leads to same problem that ctime
and mtime saved before doing a "cp" operation are the same as after.
