From a9623ada6f7b39ac2d567f66a496072487d8e6ec Mon Sep 17 00:00:00 2001 From: Vijaykumar M Date: Thu, 12 Dec 2013 11:40:36 +0530 Subject: pathinfo: Provide user namespace access. Locality can be now queried by unprivileged users with key "glusterfs.pathinfo". Setting both "glusterfs.pathinfo" and "trusted.glusterfs.pathinfo" on disk is prevented with this patch.
