parentdm integrity: count and display checksum failures (diff)
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.)
