[merged mm-stable] alloc_tag-move-memory_allocation_profiling_sysctls-into-rodata.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: alloc_tag: move memory_allocation_profiling_sysctls into .rodata
has been removed from the -mm tree.  Its filename was
     alloc_tag-move-memory_allocation_profiling_sysctls-into-rodata.patch

This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: alloc_tag: move memory_allocation_profiling_sysctls into .rodata
Date: Mon, 15 Dec 2025 16:47:37 +0100

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).
