Well, kmalloc(0) has always been legal and traditionally returned a pointer to a smallest non-zero sized object. We did try to make kmalloc(0) illegal for a while but ended up fixing up a bunch of call-sites for little or no gain. I did propose that kmalloc(0) should return NULL but Linus and others pointed out that we can do better and not mix up out-of-memory and zero-sized allocations. - 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/
