Huh, sorry, no - my bad. I was thinking of the code, not the
description at all.

For example here:

I think you should adjust the indentation to match - or did it just get
mangled in my mail? It looks *further* indented now, when it should be
less (to after the opening parenthesis). Similarly in various other
places.

And perhaps for long things like

> +static inline struct crypto_aead *ieee80211_aes_key_setup_encrypt(
> +ÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂconst u8 key[], size_t key_len,

> +ÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂconst u8 key[], size_t key_len, size_t authsize);

it might be better to write

static inline struct crypto_aead *
ieee80211_aes_key_setup_encrypt(const u8 key[], ...)

and

struct crypto_aead *
aead_key_setup_encrypt(const char *alg, ...)


respectively, depending on how far you have to indent to break lines
etc.

Anyway, I'm nitpicking.

Unrelated to this, I'm not sure whose tree this should go through -
probably Herbert's (or DaveM's with his ACK? not sure if there's a
crypto tree?) or so?
