[PATCH v2 0/2] scripts/gdb/symbols: make BPF debug info available to GDB

[Ilya Leoshkevich <iii@linux.ibm.com>]

v1: https://lore.kernel.org/bpf/20250710115920.47740-1-iii@linux.ibm.com/
v1 -> v2: Hide the feature behind the -bpf flag for performance reasons
          (Jan).
          Fix running lx-symbols twice.


Hi,

This series greatly simplifies debugging BPF progs when using QEMU
gdbstub by providing symbol names, sizes, and line numbers to GDB.

Patch 1 adds radix tree iteration, which is necessary for parsing
prog_idr. Patch 2 is the actual implementation; its description
contains some details on how to use this.

Best regards,
Ilya
