Maybe. Luckily, <smile> I don't have to deal with the patches that would be generated by this message. Some people are going to view patches for this as useless noise. Couple of things: It's kind of interesting how the messages vary by subsystem. Let me know if you want any breakdowns. And there are a small number of false positives for this "Missing a blank line" test with declarations like: typedef *foo; DECLARE_BITMAP(foo); __DECL_REG(foo); LIST_HEAD(foo); So there could be a minor improvement to the test. I looked at some of the results using: This sort of match stands out a bit: ---> arch/tile/lib/spinlock_32.c:68: { u32 iterations = 0; while (arch_spin_is_locked(lock)) delay_backoff(iterations++); } Instances like this may be fine, but adding blank lines to very short functions with a single declaration just adds to the overall line count. I've no strong opinion of the need to write code like: { u32 iterations = 0; while (arch_spin_is_locked(lock)) delay_backoff(iterations++); } _______________________________________________ devel mailing list de...@linuxdriverproject.org http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
