From 1058ef0dcb7116fc49270131fda3037fddcc6595 Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Wed, 5 Sep 2018 12:24:00 -0700 Subject: fscrypt: remove CRYPTO_CTR dependency fscrypt doesn't use the CTR mode of operation for anything, so there's no need to select CRYPTO_CTR. It was added by commit 71dea01ea2ed ("ext4 crypto: require CONFIG_CRYPTO_CTR if ext4 encryption is enabled"). But, I've been unable to identify the arm64 crypto bug it was supposedly working around. I suspect the issue was seen only on some old Android device kernel (circa 3.10?). So if the fix wasn't mistaken, the real bug is probably already fixed. Or maybe it was actually a bug in a non-upstream crypto driver. So, remove the dependency. If it turns out there's actually still a bug, we'll fix it properly.
