+#   [PATCH] new valid_signal() function
+#   
+#   This patch adds a new function valid_signal() that tests if its argument is
+#   a valid signal number.
+#   
+#   The reasons for adding this new function are:
+#   
+#   - some code currently testing _NSIG directly has off-by-one errors.
+#     Using this function instead avoids such errors.
+#   
+#   - some code currently tests unsigned signal numbers for <0 which is
+#     pointless and generates warnings when building with gcc -W.  Using this
+#     function instead avoids such warnings.
+#   
+#   I considered various places to add this function but eventually settled on
+#   include/linux/signal.h as the most logical place for it.  If there's some
+#   reason this is a bad choice then please let me know (hints as to a better
+#   location are then welcome of course).
