Subject: [PATCH v2] macintosh: declare ctl_table as const
Date: Tue, 17 Dec 2024 21:55:41 -0500 [thread overview]
Message-ID: <20241217-constify_ctl_table-v1-1-402ebceaeb8e@gmail.com> (raw)
Since commit 7abc9b53bd51 ("sysctl: allow registration of const struct
ctl_table"), the sysctl registration API allows struct ctl_table variables
to be placed into read-only memory.
mac_hid_files is registered as a sysctl table and should be treated as
read-only. By declaring the mac_hid_files structure as const, we ensure
that it cannot be accidentally modified. This change improves safety.
