Subject: [PATCH] journal: Drop monotonicity check when appending to journal
 file

Remove the check that triggers rotation of the journal file when the
arriving log entry had a monotonic timestamp smaller that the previous
log entry. This check causes unnecessary rotations when journal-remote
was receiving from multiple senders, therefore monotonicity can not be
guaranteed. Also, it does not offer any useful functionality for
systemd-journald.
