[PATCH 1/2] yama: Make sysctl table const

From: Ricardo B. Marliere <hidden>
Date: 2025-01-23 19:35:44
Also in: lkml
Subsystem: security subsystem, the rest, yama security module · Maintainers: Paul Moore, James Morris, "Serge E. Hallyn", Linus Torvalds, Kees Cook

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 yama_sysctl_table to be declared at build time,
instead of having to be dynamically allocated at boot time.
