Target needs access to mapped device

[Abhishek Gupta <agupta@xxxxxxxxx>]

Hi everyone,

I need to be able to set a logical device to read-only from the 
target of the logical device. In other words, I need the following 
function in dm-table.c:

void dm_table_set_mode(struct dm_table *t, int mode)
{
	t->mode = mode;
}

There is already a function dm-table.c:dm_table_get_mode(). Will it be 
feasible to 
include its counterpart too?

Thanks

Abhishek
