linux stack trace of running process

? The runtime environment of the C ++ language is a stack-based environment. The trace stack is used to track and print the called functions, variables, and return addresses when the program is running, the stack trace in the C ++ exception is to

Call Trace can print the current stack of function calls. kernel state Call Trace There are three types of error in the kernel state, namely bugs, oops and panic. Bugs are minor errors, such as calling sleep during spin_lock, causing a potential
