Subject: [PATCH v3 08/23] bsd-user: Implement target_set_brk function in bsd-mem.c instead of os-syscall.c
Date: Sat,  9 Sep 2023 22:36:49 +0300	[thread overview]
Message-ID: <20230909193704.1827-9-kariem.taha2.7@gmail.com> (raw)
In-Reply-To: <20230909193704.1827-1-kariem.taha2.7@gmail.com>

From: Stacey Son <sson@FreeBSD.org>

The definitions and variables names matches the corresponding ones in
linux-user/syscall.c, for making later implementation of do_obreak easier
