Otherwise just go ahead. > > My patch is already in Pekka's slab-2.6.git tree at http://git.kernel.org/?p=linux/kernel/git/penberg/slab-2.6.git;a=commit;h=fa5ec8a1f66f3c2a3af723abcf8085509c9ee682 You had proposed http://marc.info/?l=linux-kernel&m=124725166205814, which moves the mask to kmem_cache_open() and calls calculate_sizes() twice. That eliminates DEBUG_FLAGS_SIZE, but I don't see that define as being troublesome since we must define DEBUG_FLAGS to specify what options add metdata anyway. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
