NAME
       function::sprintbacktrace - Return stack back trace as string

SYNOPSIS
           sprintbacktrace:string()

ARGUMENTS
       None

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