Subject: [PATCH 0/2] md/raid6: improvements for ARM/arm64
Date: Thu, 13 Jul 2017 18:15:59 +0100 [thread overview]
Message-ID: <20170713171601.25440-1-ard.biesheuvel@linaro.org> (raw)
1. Use a faster algorithm for the delta syndrome
2. Implement recovery routines in NEON
As before, NEON intrinsics are used, which means the same code can be
compiled for ARM as well as arm64.
Given that there does not seem to be a maintainer for lib/raid6, could
we take this through one of the ARM trees instead?
