Subject: Re: [PATCH] crypto: crct10dif - remove from crypto API


Eric,

> Remove the "crct10dif" shash algorithm from the crypto API. It has no
> known user now that the lib is no longer built on top of it. It has no
> remaining references in kernel code. The only other potential users
> would be the usual components that allow specifying arbitrary hash
> algorithms by name, namely AF_ALG and dm-integrity. However there are
> no indications that "crct10dif" is being used with these components.
> Debian Code Search and web searches don't find anything relevant, and
> explicitly grepping the source code of the usual suspects (cryptsetup,
> libell, iwd) finds no matches either. "crc32" and "crc32c" are used in
> a few more places, but that doesn't seem to be the case for
> "crct10dif".
