From b22d81fb683f22304f017b1b1674e6937bdd6d49 Mon Sep 17 00:00:00 2001 From: Joel Granados Date: Tue, 9 Dec 2025 12:48:27 +0100 Subject: [PATCH] alloc_tag: move memory_allocation_profiling_sysctls into .rodata Remove the change in file mode permissions done before initializing the sysctl. It is not necessary as the writing of the kernel variable will be blocked by the proc_mem_profiling_handler when writing is disallowed (also controlled by mem_profiling_support).
