+The following is a list of symbols whose exports are unused in the kernel
+tree and will be removed. Unused symbols are both increasing the size of
+the kernel binary and are often a sign of a "wrong API"
+
+When adding a symbol, change to EXPORT_UNUSED_SYMBOL{_GPL} in the source
+and schedule for removal in the first stable version the unused symbol is
+marked in + 3. This will give out of tree code ~9 months to stop using the
+export or make a case why the export should be kept.
+
+CONFIG_UNUSED_SYMBOLS is provided to enable unused symbol exports.
+
+Please include the following:
+
+What: the_symbol
+Where: filename the symbol is exported from
+When: next stable version+3
+Why: a reason would be nice
+
+---------------------------
+
+What: __inet_hash_connect
+Where: net/ipv4/inet_hashtables.c
+When: 2.6.28
+Why: No in tree users
+
+---------------------------
+
+What: io_delay_type
+Where: arch/x86/kernel/io_delay.c
+When: 2.6.28
+Why: No in tree users
