We currently get the following warning: debugfs.c:105:54: error: '%d' directive output may be truncated writing between 1 and 11 bytes into a region of size 8 [-Werror=format-truncation=] snprintf(name, sizeof(name), "supply-%d", i); ^~ debugfs.c:105:46: note: directive argument in the range [-2147483644, 2147483646] snprintf(name, sizeof(name), "supply-%d", i); ^~~~~~~~~~~ debugfs.c:105:17: note: 'snprintf' output between 9 and 19 bytes into a destination of size 15 snprintf(name, sizeof(name), "supply-%d", i); Fix this and another potential issue it by increasing size of the arrays.
