This patch series introduces and extends several userspace commands used with netlink protocol. Touch block command allows to write data and return sampled data to the userspace. Extended search and alarm seach commands to return list of slave devices found during given search. List masters command allows to send all registered master IDs to the userspace. Great thanks to Paul Alfille (owfs) who tested this implementation and wrote w1-to-network daemon http://sourceforge.net/projects/w1repeater/ and Frederik Deweerdt and Randy Dunlap for review. This patch: Returns list of registered bus master devices.
