Hi all,
After merging the rcu tree, today's linux-next build (htmldocs) produced
this warning:
Documentation/RCU/Design/Data-Structures/Data-Structures.rst
:992: ERROR: Malformed table.
+-----------------------------------------------------------------------+
| **Quick Quiz**: |
+-----------------------------------------------------------------------+
| Why not simply combine the ``->nesting`` and |
| ``->nmi_nesting`` counters into a single counter that just |
| counts the number of reasons that the corresponding CPU is non-idle? |
+-----------------------------------------------------------------------+
| **Answer**: |
+-----------------------------------------------------------------------+
| Because this would fail in the presence of interrupts whose handlers |
| never return and of handlers that manage to return from a made-up |
| interrupt. |
+-----------------------------------------------------------------------+
