Subject: [PATCH] tty: Make sysctl table const
Date: Fri, 13 Dec 2024 16:35:05 -0300 [thread overview]
Message-ID: <20241213-sysctl_const-tty-v1-1-2e2bcec77f85@suse.com> (raw)
Since commit 7abc9b53bd51 ("sysctl: allow registration of const struct
ctl_table"), the sysctl registration API allows for struct ctl_table to be
in read-only memory. Move tty_table to be declared at build time, instead
of having to be dynamically allocated at boot time.
