[S+Q3 07/23] slub: Use kmem_cache flags to detect if slab is in debugging mode.
The cacheline with the flags is reachable from the hot paths after the percpu allocator changes went in. So there is no need anymore to put a flag into each slab page. Get rid of the SlubDebug flag and use the flags in kmem_cache instead. Acked-by: David Rientjes <rientjes(a)> Signed-off-by: Christoph La... 3 Aug 2010 23:31
[S+Q3 20/23] slub: Shared cache to exploit cross cpu caching abilities.
Strictly a performance enhancement by better tracking of objects that are likely in the lowest cpu caches of processors. SLAB uses one shared cache per NUMA node or one globally. However, that is not satifactory for contemporary cpus. Those may have multiple independent cpu caches per node. SLAB in these situatio... 3 Aug 2010 23:31
[S+Q3 19/23] slub: Object based NUMA policies
Slub applies policies and cpuset restriction currently only on the page level. The patch here changes that to apply policies to individual allocations (like SLAB). This comes with a cost of increased complexiy in the allocator. The allocation does not build alien queues (later patch) and is a bit ineffective sinc... 3 Aug 2010 23:31
[S+Q3 10/23] slub: Allow removal of slab caches during boot V2
Serialize kmem_cache_create and kmem_cache_destroy using the slub_lock. Only possible after the use of the slub_lock during dynamic dma creation has been removed. Then make sure that the setup of the slab sysfs entries does not race with kmem_cache_create and kmem_cache destroy. If a slab cache is removed befo... 3 Aug 2010 23:31
[S+Q3 05/23] Subjec Slub: Force no inlining of debug functions
Compiler folds the debgging functions into the critical paths. Avoid that by adding noinline to the functions that check for problems.

[S+Q3 13/23] slub: Move gfpflag masking out of the hotpath
Move the gfpflags masking into the hooks for checkers and into the slowpaths. gfpflag masking requires access to a global variable and thus adds an additional cacheline reference to the hotpaths. If no hooks are active then the gfpflag masking will result in code that the compiler can toss out. Signed-off-by: ... 3 Aug 2010 23:31
fix corruption of hibernation caused by reusing swap at saving image

[PATCH v2 1/3] block, partition: add partition_meta_info to hd_struct
