Subject: [PATCH v3 07/12] parisc: add `const` to mmap_upper_limit() parameter
Date: Mon, 1 Sep 2025 08:12:18 +0200 [thread overview]
Message-ID: <20250901061223.2939097-8-max.kellermann@ionos.com> (raw)
In-Reply-To: <20250901061223.2939097-1-max.kellermann@ionos.com>
For improved const-correctness. This piece is necessary to make the
`rlim_stack` parameter to mmap_base() const.
