Subject: [RFC PATCH v2 2/8] arm64/signal: Update the comment in preserve_sve_context
Date: Thu, 13 Jun 2019 17:16:50 +0100 [thread overview]
Message-ID: <20190613161656.20765-3-julien.grall@arm.com> (raw)
In-Reply-To: <20190613161656.20765-1-julien.grall@arm.com>
The SVE state is saved by fpsimd_signal_preserve_current_state() and not
preserve_fpsimd_context(). Update the comment in preserve_sve_context to
reflect the current behavior.
