Building bpftool yields the following complaint:
pids.c: In function 'emit_obj_refs_json':
pids.c:175:80: warning: declaration of 'json_wtr' shadows a global declaration [-Wshadow]
175 | void emit_obj_refs_json(struct obj_refs_table *table, __u32 id, json_writer_t *json_wtr)
| ~~~~~~~~~~~~~~~^~~~~~~~
In file included from pids.c:11:
main.h:141:23: note: shadowed declaration is here
141 | extern json_writer_t *json_wtr;
| ^~~~~~~~
Let's rename the variable.
v2:
- Rename the variable instead of calling the global json_wtr directly.
