2006-01-11[PATCH] fix/simplify mutex debugging codeDavid Woodhouse
Let's switch mutex_debug_check_no_locks_freed() to take (addr, len) as arguments instead, since all its callers were just calculating the 'to' address for themselves anyway...

2005-11-07[PATCH] slab: don't BUG on duplicated cacheAndrew Morton
slab presently goes BUG if someone tries to register an already-registered cache. But this can happen if the user accidentally loads a module which is already statically linked into the kernel. Nuking the kernel is rather a harsh reaction. Change it into a warning, and just fail the kmem_cache_alloc() attempt. If the module is well-behaved, the modprobe will fail and all is well. Notes: - Swaps the ranking of cache_chain_sem and lock_cpu_hotplug(). Doesn't seem important.

2005-09-22[PATCH] __kmalloc: Generate BUG if size requested is too large.Christoph Lameter
I had an issue on ia64 where I got a bug in kernel/workqueue because kzalloc returned a NULL pointer due to the task structure getting too big for the slab allocator. Usually these cases are caught by the kmalloc macro in include/linux/slab.h. Compilation will fail if a too big value is passed to kmalloc. However, kzalloc uses __kmalloc which has no check for that. This patch makes __kmalloc bug if a too large entity is requested.

2005-09-22[PATCH] slab: fix handling of pages from foreign NUMA nodesChristoph Lameter
The numa slab allocator may allocate pages from foreign nodes onto the lists for a particular node if a node runs out of memory. Inspecting the slab->nodeid field will not reflect that the page is now in use for the slabs of another node. This patch fixes that issue by adding a node field to free_block so that the caller can indicate which node currently uses a slab. Also removes the check for the current node from kmalloc_cache_node since the process may shift later to another node which may lead to an allocation on another node than intended.

2005-09-14[PATCH] Fix slab BUG_ON() triggered by change in array cache sizeAlok Kataria
With the new changes that we made in the initialization of the slab allocator, we first setup the cache from which array caches are allocated, and then the cache, from which kmem_list3's are allocated. Now if the array cache comes from a cache in which objsize > 32, (in this instance size-64) then, first size-64 cache will be allocated and then the size-128 (if this is the cache from which kmem_list3's are going to be allocated). So with these new changes, we are not guaranteed that we will be initializing the malloc_sizes array in a serialized order. Thus there is a bug in __find_general_cachep, as we are checking whether the first cache_sizes ptr is NULL. This is replaced by checking whether the array-cache cache is initialized. Attached is a patch which does that. Boots fine on a x86-64, with DEBUG_SPIN, DEBUG_SLAB, and preempt. Attached is a patch which does that.

2005-09-09[PATCH] Numa-aware slab allocator V5Christoph Lameter
The NUMA API change that introduced kmalloc_node was accepted for 2.6.12-rc3. Now it is possible to do slab allocations on a node to localize memory structures. This API was used by the pageset localization patch and the block layer localization patch now in mm. The existing kmalloc_node is slow since it simply searches through all pages of the slab to find a page that is on the node requested. The two patches do a one time allocation of slab structures at initialization and therefore the speed of kmalloc node does not matter. This patch allows kmalloc_node to be as fast as kmalloc by introducing node specific page lists for partial, free and full slabs. Slab allocation improves in a NUMA system so that we are seeing a performance gain in AIM7 of about 5% with this patch alone. More NUMA localizations are possible if kmalloc_node operates in an fast way like kmalloc.

2005-06-21[PATCH] Periodically drain non local pagesetsChristoph Lameter
The pageset array can potentially acquire a huge amount of memory on large NUMA systems. F.e. on a system with 512 processors and 256 nodes there will be 256*512 pagesets. If each pageset only holds 5 pages then we are talking about 655360 pages.With a 16K page size on IA64 this results in potentially 10 Gigabytes of memory being trapped in pagesets. The typical cases are much less for smaller systems but there is still the potential of memory being trapped in off node pagesets. Off node memory may be rarely used if local memory is available and so we may potentially have memory in seldom used pagesets without this patch. The slab allocator flushes its per cpu caches every 2 seconds. The following patch flushes the off node pageset caches in the same way by tying into the slab flush. The patch also changes /proc/zoneinfo to include the number of pages currently in each pageset.

2005-05-01[PATCH] add kmalloc_node, inline cleanupManfred Spraul
The patch makes the following function calls available to allocate memory on a specific node without changing the basic operation of the slab allocator: kmem_cache_alloc_node(kmem_cache_t *cachep, unsigned int flags, int node); kmalloc_node(size_t size, unsigned int flags, int node); in a similar way to the existing node-blind functions: kmem_cache_alloc(kmem_cache_t *cachep, unsigned int flags); kmalloc(size, flags); kmem_cache_alloc_node was changed to pass flags and the node information through the existing layers of the slab allocator (which lead to some minor rearrangements). The functions at the lowest layer (kmem_getpages, cache_grow) are already node aware. Also __alloc_percpu can call kmalloc_node now. Performance measurements (using the pageset localization patch) yields: w/o patches: Tasks jobs/min jti jobs/min/task real cpu 1 484.27 100 484.2736 12.02 1.97 Wed Mar 30 20:50:43 2005 100 25170.83 91 251.7083 23.12 150.10 Wed Mar 30 20:51:06 2005 200 34601.66 84 173.0083 33.64 294.14 Wed Mar 30 20:51:40 2005 300 37154.47 86 123.8482 46.99 436.56 Wed Mar 30 20:52:28 2005 400 39839.82 80 99.5995 58.43 580.46 Wed Mar 30 20:53:27 2005 500 40036.32 79 80.0726 72.68 728.60 Wed Mar 30 20:54:40 2005 600 44074.21 79 73.4570 79.23 872.10 Wed Mar 30 20:55:59 2005 700 44016.60 78 62.8809 92.56 1015.84 Wed Mar 30 20:57:32 2005 800 40411.05 80 50.5138 115.22 1161.13 Wed Mar 30 20:59:28 2005 900 42298.56 79 46.9984 123.83 1303.42 Wed Mar 30 21:01:33 2005 1000 40955.05 80 40.9551 142.11 1441.92 Wed Mar 30 21:03:55 2005 with pageset localization and slab API patches: Tasks jobs/min jti jobs/min/task real cpu 1 484.19 100 484.1930 12.02 1.98 Wed Mar 30 21:10:18 2005 100 27428.25 92 274.2825 21.22 149.79 Wed Mar 30 21:10:40 2005 200 37228.94 86 186.1447 31.27 293.49 Wed Mar 30 21:11:12 2005 300 41725.42 85 139.0847 41.84 434.10 Wed Mar 30 21:11:54 2005 400 43032.22 82 107.5805 54.10 582.06 Wed Mar 30 21:12:48 2005 500 42211.23 83 84.4225 68.94 722.61 Wed Mar 30 21:13:58 2005 600 40084.49 82 66.8075 87.12 873.11 Wed Mar 30 21:15:25 2005 700 44169.30 79 63.0990 92.24 1008.77 Wed Mar 30 21:16:58 2005 800 43097.94 79 53.8724 108.03 1155.88 Wed Mar 30 21:18:47 2005 900 41846.75 79 46.4964 125.17 1303.38 Wed Mar 30 21:20:52 2005 1000 40247.85 79 40.2478 144.60 1442.21 Wed Mar 30 21:23:17 2005 Signed-off-by: Christoph Lameter <christoph@lameter.com> Signed-off-by: Manfred Spraul <manfred@colorfullife.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
