Subject: [9front] [PATCH] exportfs: fix clunk of first attach with -S
Date: Sun, 16 Oct 2022 19:35:30 +0000 [thread overview]
Message-ID: <71D81C816314EDF35CE6A906B468E97B@mforney.org> (raw)
0 is a valid mid so should not be used as a nil value, since then the
first mount (mid=0) will never be unmounted.
