From 5916a22b83041b07d63191fe06206ae0fff6ec7a Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Thu, 22 Jun 2017 11:32:45 -0700 Subject: dm: constify argument arrays The arrays of 'struct dm_arg' are never modified by the device-mapper core, so constify them so that they are placed in .rodata. (Exception: the args array in dm-raid cannot be constified because it is allocated on the stack and modified.)
