From 3550a516d07dda4786c63e86f64f4f440db58782 Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Tue, 28 Aug 2007 20:28:55 +0200 Subject: [PATCH] kbuild: __extension__ support in genksyms (fix unknown CRC warning) Recently the __extension__ keyword has been introduced in the kernel. Teach genksyms about this keyword so it can generate correct CRC for exported symbols that uses a symbol marked __extension__. For now only the typedef variant: __extension__ typedef ... is supported. Later we may add more variants as needed. This patch contains the actual source file changes. The following patch will hold modifications to the generated files (*_shipped) and only after the second patch the fix has effect.
