[PATCH] security: keys: Make sysctl table const

From: Ricardo B . Marliere
Date: Thu Jan 23 2025 - 14:50:26 EST


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