What does '0' mean? I think this should definitely be an enum or at
least #define.
The first element of the array is "ima". Should I define two macros
similar to kernel_read_file_id and kernel_read_file_str for just two
strings?
I would introduce an enum like enum hash_algo:
https://elixir.bootlin.com/linux/latest/source/include/uapi/linux/hash_info.h#L38
And an array like hash_algo_name:
https://elixir.bootlin.com/linux/latest/source/crypto/hash_info.c#L12
thanks,
Mimi
