Well slub returns an error code if it fails. I am all in favor of making it consistent. The indication in SLAB that the slab is empty may be useful. May return error code or the number of slab pages in use? Some of the code that is shared by the allocators here could be moved into mm/slab_common.c. Put kmem_cache_shrink there and then have __kmem_cache_shrink to the allocator specific things? x -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
