Bug#953860: systemd-journald keeps open deleted mapped files - leak?

[Russell Coker]

Package: systemd
Version: 245-2
Severity: normal

/var/log/journal/68f1b89bf8c73b0ed9ed905f535fa641/user-1000 at 802af85f15f0436cbbf371c9ef25cc3d-0000000000000000-0000000000000000.journal

On this system the above file is deleted but mapped, is this operating as
designed?  There are currently no processes of user 1000 running.  When I login
with the user who has uid 1000 it doesn't change anything, that deleted file is
still mapped.
