Donenfeld <Jason@xxxxxxxxx> > Cc: stable@xxxxxxxxxxxxxxx For context, in your commit message can you include a link to my email mentioning Android's Speck decision (https://marc.info/?l=linux-crypto-vger&m=153359499015659)? Also: "speck" => "Speck". Also I think the fscrypt code points should be reserved so they don't get reused for something else: #define FS_ENCRYPTION_MODE_SPECK128_256_XTS 7 /* removed */ #define FS_ENCRYPTION_MODE_SPECK128_256_CTS 8 /* removed */ Otherwise: Acked-by: Eric Biggers <ebiggers@xxxxxxxxxx> For the record, I think the statements Paul and I have made evaluating Speck from a technical perspective remain substantially accurate. However, clearly today there are more than just technical considerations when choosing cryptographic primitives. So ultimately, enough people didn't *want* Speck that we weren't able to offer it, even though it was only meant to replace no encryption. We've also designed and proposed an alternative solution for the ARMv7 disk encryption use case, HPolyC. So given the above, and that I no longer know of any specific users of the Speck code (so in principle it can still be removed without breaking userspace), and that it's possible that similar considerations will make Speck difficult for others to use, and that some people heavily object to Speck being optionally supported in the kernel at all, I'm okay with it being removed...
