[PATCH] apparmor: Make sysctl table const

From: Ricardo B . Marliere
Date: Thu Jan 23 2025 - 14:57:35 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 apparmor_sysctl_table to be declared at build
time, instead of having to be dynamically allocated at boot time.
