-          Normally kallsyms only contains the symbols of functions, for nicer
-          OOPS messages.  Some debuggers can use kallsyms for other

+          Normally kallsyms only contains the symbols of functions for nicer
+          OOPS messages and backtraces (i.e., symbols from the text and inittext
+          sections). This is sufficient for most cases. And only in very rare
+          cases (e.g., when a debugger is used) all symbols are required (e.g.,
+          names of variables from the data sections, etc).

-       help
-          If kallsyms is not working correctly, the build will fail with
-          inconsistent kallsyms data.  If that occurs, log a bug report and
-          turn on KALLSYMS_EXTRA_PASS which should result in a stable build.
-          Always say N here unless you find a bug in kallsyms, which must be
-          reported.  KALLSYMS_EXTRA_PASS is only a temporary workaround while
-          you wait for kallsyms to be fixed.
+          This option makes sure that all symbols are loaded into the kernel
+          image (i.e., symbols from all sections) in cost of increased kernel
+          size (depending on the kernel configuration, it may be 300KiB or
+          something like this).
 
+          Say N unless you really need all symbols.
