This patch consists of the files
child_propogate.sh - Propagates the contents of the child sysfs to parentNS.
parent_share.sh - Creates a sharable volume of the sysfs for child to access.
parent_view.sh - Parent NS verifies the contents of the child sysfs.
sysfsview.c - Basic program to create namespaces for sysfs checking
