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

From: Wen Yang <[email protected]>

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.
