Wiedemann" <bwiedem...@suse.de> Date: Sun, 1 Jan 2023 14:43:26 +0100 Subject: [PATCH] Re-open lock file before locking because the previous 'withlock' cleanup function might have deleted the file and since we still held a handle to the old deleted file, we could run concurrently with a 3rd 'withlock' which creates a new file.
