Meminspect - Kernel memory selection and inspection mechanism
summary
Meminspect provides a compact table of annotated kernel regions so consumers can produce a tiny core image instead of a full kdump; it implements a compile‑time mespect_entry macro for static symbols, a runtime mark_inspect memblock API for memblock allocations, and register/traverse + notifier hooks so firmware or drivers can copy regions. Qualcomm’s mini‑dump and the Pixel kinfo flow already use it to produce ~2–3 MB dumps that load into crash tool for analysis, and patches are available for upstream review.
