Subject: [PATCH nolibc 03/18] tools/nolibc: make sys_mmap() automatically use the right __NR_mmap definition
Date: Wed, 31 Aug 2022 11:21:33 -0700 [thread overview]
Message-ID: <[email protected]> (raw)
In-Reply-To: <20220831182113.GA2697286@paulmck-ThinkPad-P17-Gen-1>
From: Willy Tarreau <[email protected]>
__NR_mmap2 was used for i386 but it's also needed for other archs such
as RISCV32 or ARM. Let's decide to use it based on the __NR_mmap2
definition as it's not defined on other archs.
