From 03e06e68ff76294e53ffa898cb844d2a997b043e Mon Sep 17 00:00:00 2001 From: Ram Pai Date: Mon, 7 Nov 2005 17:19:33 -0500 Subject: [PATCH] introduce shared mounts This creates shared mounts. A shared mount when bind-mounted to some mountpoint, propagates mount/umount events to each other. All the shared mounts that propagate events to each other belong to the same peer-group.
