Hi list, Sorry for the spam. Just curious what are the ways/tools filesystem experts using for debugging. I sometimes use Ftrace, Kgtp and printk. Seldomly use virtualbox with kgdb. But each way has it short-comes. Just want to get some enlightenment about debugging skills, especially from you Filesystem experts. Thank you!
