在 kernel 下打出 有帶參數的log。 怪異現象與解決方式。

code

2717         battery_log(BAT_LOG_CRTI, "youchihwang abc10010 xxxaaa8-2
");
2718         battery_log(BAT_LOG_CRTI, "youchihwang abc10010 xxxaaa8-3
");
.....
.....
.....
2731         battery_log(BAT_LOG_CRTI, "youchihwang5 CHR_Type_num=%d
",
2732                         CHR_Type_num);
2733         battery_log(BAT_LOG_CRTI, "youchihwang6 CHR_Type_num=%d
",
2734                         CHR_Type_num);

小結：

         在 kernel 中打 log，

         不論是帶有參數的 log，或是沒有帶參數的 log，

         在其後加上 " " 或 " " 的結果都是一樣的，

         都會移到新的一行。

小結：

         在 kernel 中要打出有帶參數的 log （如上），

         比對 前 5 個 與 後 3 個可得知，

         在 "%" 前需加上 "=" 。
