crypto: Drop stale usages in various help texts

[PATCH 0/5] crypto: Drop stale usages in various help texts

Posted by Geert Uytterhoeven 1 month, 2 weeks ago

	Hi all,

This patch series drops stale references to subsystems that are using
various crypto algoritms.  It was triggered by "make oldconfig" in
v7.0-rc1 showing new prompts about BLAKE2b, SHA-256, xxHash, and CRC32c
algorithms.  When querying these symbols, the corresponding help texts
incorrectly claim they are used by btrfs.

Notw that even if correct, there is no need for such references, as all
users should select the needed symbols anyway.

  crypto: Drop stale CRYPTO_BLAKE2B usage
  crypto: Drop stale CRYPTO_SHA256 usage
  crypto: Drop stale CRYPTO_XXHASH usage
  crypto: Drop stale CRYPTO_CRC32C usage
  crypto: Drop stale CRYPTO_CRC32 usage

Thanks for cleaning this up!

If there are no objections I'd like take these through libcrypto-fixes,
given that they are related to the library conversions.

Applied to https://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux.git/log/?h=libcrypto-fixes

I adjusted the commit titles to make it clear that the changes are to
the help text, not e.g. to selections of the symbols.
