[dm-devel] [PATCH 0 of 2] DM log userspace: Allow DM_ULOG_CTR exchange to accept devices for register

[Jonathan Brassow <jbrassow redhat com>]

The following two patches allow the dm-log-userspace module to have a
two-way communication when DM_ULOG_CTR is issued.  The outbound (kernel
-> userspace) msg sends the CTR information necessary to build the log
device.  The new inbound (userspace -> kernel) msg sends the log device
name to the kernel so the kernel can call 'dm_get_device' on it.  This
allows the necessary device dependencies to be built.
