slab: Return NULL for oversized allocations

2013-05-06T06:24:16Z

The inline path seems to have changed the SLAB behavior for very large kmalloc allocations with commit e3366016 ("slab: Use common kmalloc_index/kmalloc_size functions"). This patch restores the old behavior but also adds diagnostics so that we can figure where in the code these large allocations occur.

slab: Use common kmalloc_index/kmalloc_size functions

2013-02-01T10:32:06Z

Make slab use the common functions. We can get rid of a lot of old ugly stuff as a results. Among them the sizes array and the weird include/linux/kmalloc_sizes file and some pretty bad #include statements in slab_def.h. The one thing that is different in slab is that the 32 byte cache will also be created for arches that have page sizes larger than 4K. There are numerous smaller allocations that SLOB and SLUB can handle better because of their support for smaller allocation sizes so lets keep the 32 byte slab also for arches with > 4K pages.

slab: Simplify bootstrap

2012-12-11T10:14:27Z

The nodelists field in kmem_cache is pointing to the first unused object in the array field when bootstrap is complete. A problem with the current approach is that the statically sized kmem_cache structure use on boot can only contain NR_CPUS entries. If the number of nodes plus the number of cpus is greater then we would overwrite memory following the kmem_cache_boot definition. Increase the size of the array field to ensure that also the node pointers fit into the array field. Once we do that we no longer need the kmem_cache_nodelists array and we can then also use that structure elsewhere.
