15 Returns a simple (kernel) backtrace. One line per address. Includes the
16 symbol name (or hex address if symbol couldn't be resolved) and module
17 name (if found). Includes the offset from the start of the function if
18 found, otherwise the offset will be added to the module (if found,
19 between brackets). Returns the backtrace as string (each line
20 terminated by a newline character). Note that the returned stack will
21 be truncated to MAXSTRINGLEN, to print fuller and richer stacks use
22 print_backtrace. Equivalent to sprint_stack(backtrace), but more
23 efficient (no need to translate between hex strings and final backtrace
24 string).
