The patch titled w1: add list masters w1 command has been removed from the -mm tree. Its filename was w1-add-list-masters-w1-command.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: w1: add list masters w1 command From: Evgeniy Polyakov <zbr@xxxxxxxxxxx> 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.
