From 9cb1397d585c28c2acff06a6002fc2c8db19a80d Mon Sep 17 00:00:00 2001 From: Rickard Strandqvist Date: Thu, 1 Jan 2015 18:52:57 +0100 Subject: dm thin metadata: remove unused dm_pool_get_data_block_size() The thin-pool target doesn't display the data block size as part of its table status, unlike the dm-cache target, so there is no need for dm_pool_get_data_block_size(). This was found using cppcheck.
