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
