I have convinced DYNAMIC_DEBUG code to not need about 15% of its __dyndbg section, about 30kb on my test kernel. This memory is not kmalloc'd, so krealloc wont work. (I tried anyway, on a loaded module, it panicd) Is there a way to return a chunk of init .data memory to general use ? heres the patchset; https://lore.kernel.org/lkml/20210529200029.205306-1-jim.cromie@xxxxxxxxx/
