From: pengdonglin <[email protected]> The trace_btf.c file provides BTF helper functions used by the ftrace subsystem. This change makes its compilation solely dependent on CONFIG_DEBUG_INFO_BTF, allowing features like funcgraph-retval to also utilize these helpers.
Additionally, the redundant dependency on CONFIG_PROBE_EVENTS_BTF_ARGS is removed, as CONFIG_DEBUG_INFO_BTF already depends on CONFIG_BPF_SYSCALL.
