From ecd10aa42819cd5dcf639d25575e95a5bda8d08a Mon Sep 17 00:00:00 2001 From: Jan Kara <jack@suse.cz> Date: Wed, 21 Feb 2018 17:59:31 +0100 Subject: udf: Apply uid/gid mount options also to new inodes & chown MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Currently newly created files belong to current user despite uid=<number> / gid=<number> mount options. This is confusing to users (as owner of the file will change after remount / eviction from cache) and also inconsistent with e.g. FAT with the same mount option. So apply uid=<number> and gid=<number> also to newly created inodes and similarly as FAT disallow to change owner of the file in this case.
