Subject: [PATCH 00/11] sysctl: treewide: constify ctl_table argument of
sysctl handlers
* Patch 1 is a bugfix for the stack_erasing sysctl handler
* Patches 2-10 change various helper functions throughout the kernel to
be able to handle 'const ctl_table'.
* Patch 11 changes the signatures of all proc handlers through the tree.
Some other signatures are also adapted, for details see the commit
message.
Only patch 1 changes any code at all.
The series was compile-tested on top of next-20230315 for
i386, x86_64, arm, arm64, riscv, loongarch and s390.
This series was split from my larger series sysctl-const series [0].
It only focusses on the proc_handlers but is an important step to be
able to move all static definitions of ctl_table into .rodata.
