right, we do have string versions in arch/blackfin/lib/ and we do want the "classical" gcc behavior here with "extern static". an extern_inline macro in compiler.h sounds good since __attribute__((__gnu_inline__)) doesnt exist in gcc-3.4.x (the other version that works for Blackfin other than gcc-4.1.x). so i guess NACK this patch since we dont want "static inline" and we dont yet support gcc-4.3 on Blackfin. -mike - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
