Subject: [PATCH 13/17] bsd-user: target_mprotect: rename prot to target_prot
Date: Fri, 2 Aug 2024 17:56:13 -0600 [thread overview]
Message-ID: <20240802235617.7971-14-imp@bsdimp.com> (raw)
In-Reply-To: <20240802235617.7971-1-imp@bsdimp.com>
Linux-user's target_mprotect uses this convention, so move to it.
