[PATCH v3 0/3] Filter out local and mapping symbols during module load

[Tiezhu Yang]

This series prevents compiler generated local and mapping symbols
from leaking into /proc/kallsyms for loaded modules. This ensures
tracing tools like bpftrace can resolve accurate kernel stacks on
architectures like LoongArch.

Based on the v2 discussion, the changes are now refactored into a
clean three-patch series to eliminate code duplication and clarify
naming.

Tiezhu Yang (3):
  module/kallsyms: Rename is_mapping_symbol() to
    is_local_mapping_symbol()
  module/kallsyms: Refactor current symbol filtering into
    is_kept_symbol()
  module/kallsyms: Filter out local and mapping symbols during module
    load
