Subject: [PATCH] arm64: wire up cachestat for arm64
Date: Thu, 11 May 2023 02:28:43 -0700 [thread overview]
Message-ID: <20230511092843.3896327-1-nphamcs@gmail.com> (raw)
In-Reply-To: <20230510195806.2902878-1-nphamcs@gmail.com>
cachestat is a new syscall that was previously wired in for most
architectures:
https://lore.kernel.org/lkml/20230503013608.2431726-1-nphamcs@gmail.com/
https://lore.kernel.org/linux-mm/20230510195806.2902878-1-nphamcs@gmail.com/
However, those patches miss arm64, which has its own syscall table in arch/arm64.
This patch wires cachestat in for arm64.
