From 73cbca6a637eb88738ea5a5cd6a611bbbca8ac19 Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Thu, 27 Apr 2017 10:11:20 -0700 Subject: [PATCH] dm block manager: remove an unused argument from dm_block_manager_create() The 'cache_size' argument of dm_block_manager_create() has never been used. Remove it along with the definitions of the constants passed as the 'cache_size' argument.
