From a58b0eb8e64b78d9315a5491955e78b1391d42e5 Mon Sep 17 00:00:00 2001 From: Ram Pai Date: Mon, 7 Nov 2005 17:20:48 -0500 Subject: [PATCH] introduce slave mounts A slave mount always has a master mount from which it receives mount/umount events. Unlike shared mount the event propagation does not flow from the slave mount to the master.
