This is a note to let you know that I've just added the patch titled crypto: skcipher - unify the crypto_has_skcipher*() functions to the 5.4-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: crypto-skcipher-unify-the-crypto_has_skcipher-functi.patch and it can be found in the queue-5.4 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 250ed9f7489ea73ea7422f38c4e4f648af200125 Author: Eric Biggers <ebiggers@xxxxxxxxxx> Date: Fri Oct 25 12:41:09 2019 -0700 crypto: skcipher - unify the crypto_has_skcipher*() functions [ Upstream commit d3ca75a8b3d77f2788e6c119ea7c3e3a1ab1e1ca ] crypto_has_skcipher() and crypto_has_skcipher2() do the same thing: they check for the availability of an algorithm of type skcipher, blkcipher, or ablkcipher, which also meets any non-type constraints the caller specified. And they have exactly the same prototype. Therefore, eliminate the redundancy by removing crypto_has_skcipher() and renaming crypto_has_skcipher2() to crypto_has_skcipher().
