Subject: [PATCH 8/9] dm vdo: Remove unused functions

From: "Dr. David Alan Gilbert" <linux@...blig.org>

get_data_vio_pool_active_discards()
get_data_vio_pool_discard_limit()
get_data_vio_pool_maximum_discards()
set_data_vio_pool_discard_limit()

are all unused since commit
a9da0fb6d8c6 ("dm vdo: remove all sysfs interfaces")

Remove them.
