From 4bef69000d93799b6b3983c45c81b3cb2cceaa99 Mon Sep 17 00:00:00 2001 From: Mike Marshall Date: Thu, 10 Aug 2017 13:50:50 -0400 Subject: [PATCH] orangefs: react properly to posix_acl_update_mode's aftermath. posix_acl_update_mode checks to see if the permissions described by the ACL can be encoded into the object's mode. If so, it sets "acl" to NULL and "mode" to the new desired value. Prior to this patch we failed to actually propagate the new mode back to the server.
