Subject: [PATCH 4.14 47/52] orangefs: report attributes_mask and attributes for statx

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Martin Brandenburg <martin@...ibond.com>

commit 7f54910fa8dfe504f2e1563f4f6ddc3294dfbf3a upstream.

OrangeFS formerly failed to set attributes_mask with the result that
software could not see immutable and append flags present in the
filesystem.
