From: Bartosz Golaszewski <[email protected]> Memory allocated with kstrdup_const() must not be passed to regular krealloc() as it is not aware of the possibility of the chunk residing in .rodata. Since there are no potential users of krealloc_const() at the moment, let's just update the doc to make it explicit.
