v1: https://lore.kernel.org/bpf/20250710115920.47740-1-iii@xxxxxxxxxxxxx/
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
