From bfc505ded01e3c57d12c6f939f352200655d8635 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Thu, 15 Sep 2016 18:26:05 -0400 Subject: [PATCH] pNFS: Fix atime updates on pNFS clients Fix the code so that we always mark the atime as invalid in nfs4_read_done(). Currently, the expectation appears to be that the pNFS drivers should always do this, with the result that most of them don't.
