Subject: [PATCH v3 8/8] linux-user/syscall: Remove ERRNO_TABLE_SIZE check
Date: Thu,  8 Jul 2021 19:05:50 +0200	[thread overview]
Message-ID: <20210708170550.1846343-9-f4bug@amsat.org> (raw)
In-Reply-To: <20210708170550.1846343-1-f4bug@amsat.org>

Now than target_to_host_errno() always return an errno, we can
remove the unused and arbitrary ERRNO_TABLE_SIZE definition.

Suggested-by: Richard Henderson <richard.henderson@linaro.org>
