Subject: [PATCH 4/8] linux-user: Convert signal number for FUTEX_FD
Date: Sun, 28 Aug 2022 19:10:02 -0700	[thread overview]
Message-ID: <20220829021006.67305-5-richard.henderson@linaro.org> (raw)
In-Reply-To: <20220829021006.67305-1-richard.henderson@linaro.org>

The val argument to FUTEX_FD is a signal number.  Convert to match
the host, as it will be converted back when the signal is delivered.
