[PATCH 5.15 131/196] NFS: Remove an incorrect revalidation in nfs4_update_changeattr_locked()

[Greg Kroah-Hartman]

From: Trond Myklebust <trond.myklebust@xxxxxxxxxxxxxxx>

commit 9d047bf68fe8cdb4086deaf4edd119731a9481ed upstream.

In nfs4_update_changeattr_locked(), we don't need to set the
NFS_INO_REVAL_PAGECACHE flag, because we already know the value of the
change attribute, and we're already flagging the size. In fact, this
forces us to revalidate the change attribute a second time for no good
reason.
This extra flag appears to have been introduced as part of the xattr
feature, when update_changeattr_locked() was converted for use by the
xattr code.

Fixes: 1b523ca972ed ("nfs: modify update_changeattr to deal with regular files")
