function::sprint_ustack - Return stack for the current task from string.
String with list of hexadecimal addresses for the current
Perform a symbolic lookup of the addresses in the given string, which is assumed
to be the result of a prior call to ubacktrace for the current task.
Returns a simple backtrace from the given hex string. 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
it is recommended to use sprint_usyms instead of this function.
