Subject: [RFC PATCH v2 0/2]  sysctl: refactor ctl_table creation and change extra{1,2} type

From: Wen Yang <wen.yang@...ux.dev>

This series introduces macros to centralize ctl_table initialization,
preparing for future type changes to extra1/extra2 fields.

Following Joel's suggestion [1], we start with helpers that work for all
existing patterns before making invasive changes.

  sysctl: introduce SYSCTL_ENTRY() helper macro
