From 295c4c2b852c83ff265466cdeba3cbbc05820e4a Mon Sep 17 00:00:00 2001 From: Sebastian Lackner Date: Tue, 28 Nov 2017 00:38:17 +0100 Subject: fusefrontend: Set owner after symlink creation in PlaintextNames mode This is already done in regular mode, but was missing when PlaintextNames mode is enabled. As a result, symlinks created by non-root users were still owned by root afterwards.
