* dm crypt: fix avoid cloned bio ref after freeOlaf Kirch2007-05-09
| | | | | | | | | | | | | Do not access the bio after generic_make_request We should never access a bio after generic_make_request - there's no guarantee it still exists.

* dm crypt: fix call to clone_initOlaf Kirch2007-05-09
| | | | | | | | | | | | | Call clone_init early We need to call clone_init as early as possible - at least before call bio_put(clone) in any error path. Otherwise, the destructor will try to dereference bi_private, which may still be NULL.

* dm raid1: one kmirrord per mirrorHolger Smolinski2007-05-09
| | | | | | | | | | | | | | | | | | | | This patch replaces the single instance of kmirrord by one instance per mirror set. This change is required to avoid a deadlock in kmirrord when the persistent dirty log of a mirror itself resides on a mirror. The single instance of kmirrord then issues a sync write to the dirty log in write_bits which gets deferred to kmirrord itself later in the call chain. But kmirrord never does the deferred work because it is still waiting for the sync write_bits. _mirror_sets is removed as it no longer needed, and we always flush the workqueue before destroying it to ensure all work is complete before destroying it.

* SLUB: include lifetime stats and sets of cpus / nodes in tracking outputChristoph Lameter2007-05-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have information about how long an object existed and about the nodes and cpus where the allocations and frees took place. Add that information to the tracking output in /sys/slab/xx/alloc_calls and /sys/slab/free_calls This will then enable slabinfo to output nice reports like this: christoph@qirst:~/slub$ ./slabinfo kmalloc-128 Slabcache: kmalloc-128 Aliases: 0 Order : 0 Sizes (bytes) Slabs Debug Memory ------------------------------------------------------------------------ Object : 128 Total : 12 Sanity Checks : On Total: 49152 SlabObj: 200 Full : 7 Redzoning : On Used : 24832 SlabSiz: 4096 Partial: 4 Poisoning : On Loss : 24320 Loss : 72 CpuSlab: 1 Tracking : On Lalig: 13968 Align : 8 Objects: 20 Tracing : Off Lpadd: 1152 kmalloc-128 has no kmem_cache operations kmalloc-128: Kernel object allocation ----------------------------------------------------------------------- 6 param_sysfs_setup+0x71/0x130 age=284512/284512/284512 pid=1 nodes=0-1,3 11 percpu_populate+0x39/0x80 age=283914/284428/284512 pid=1 nodes=0 21 __register_chrdev_region+0x31/0x170 age=282896/284347/284473 pid=1-1705 nodes=0-2 1 sys_inotify_init+0x76/0x1c0 age=283423 pid=1004 nodes=0 19 as_get_io_context+0x32/0xd0 age=6/247567/283988 pid=1-11782 nodes=0,2 10 ida_pre_get+0x4a/0x80 age=277666/283773/284526 pid=0-2177 nodes=0,2 24 kobject_kset_add_dir+0x37/0xb0 age=282727/283860/284472 pid=1-1723 nodes=0-2 1 acpi_ds_build_internal_buffer_obj+0xd3/0x11d age=284508 pid=1 nodes=0 24 con_insert_unipair+0xd7/0x110 age=284438/284438/284438 pid=1 nodes=0,2 1 uart_open+0x2d2/0x4b0 age=283896 pid=1 nodes=0 26 dma_pool_create+0x73/0x1a0 age=282762/282833/282916 pid=1705-1723 nodes=0 1 neigh_table_init_no_netlink+0xd2/0x210 age=284461 pid=1 nodes=0 2 neigh_parms_alloc+0x2b/0xe0 age=284410/284411/284412 pid=1 nodes=2 2 neigh_resolve_output+0x1e1/0x280 age=276289/276291/276293 pid=0-2443 nodes=0 1 netlink_kernel_create+0x90/0x170 age=284472 pid=1 nodes=0 4 xt_alloc_table_info+0x39/0xf0 age=283958/283958/283959 pid=1 nodes=1 3 fn_hash_insert+0x473/0x720 age=277653/277661/277666 pid=2177-2185 nodes=0 1 get_mtrr_state+0x285/0x2a0 age=284526 pid=0 nodes=0 1 cacheinfo_cpu_callback+0x26d/0x3e0 age=284458 pid=1 nodes=0 29 kernel_param_sysfs_setup+0x25/0x90 age=284511/284511/284512 pid=1 nodes=0-1,3 5 process_zones+0x5e/0x170 age=284546/284546/284546 pid=0 nodes=0 1 drm_core_init+0x48/0x160 age=284421 pid=1 nodes=2 kmalloc-128: Kernel object freeing ------------------------------------------------------------------------ 163 <not-available> age=4295176847 pid=0 nodes=0-3 1 __vunmap+0x6e/0xf0 age=282907 pid=1723 nodes=0 28 free_as_io_context+0x12/0x90 age=9243/262197/283474 pid=42-11754 nodes=0 1 acpi_get_object_info+0x1b7/0x1d4 age=284475 pid=1 nodes=0 1 do_acpi_find_child+0x45/0x4e age=284475 pid=1 nodes=0 NUMA nodes : 0 1 2 3 ------------------------------------------ All slabs 7 2 2 1 Partial slabs 2 2 0 0 Signed-off-by: Christoph Lameter <clameter@sgi.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* SLUB: add CONFIG_SLUB_DEBUGChristoph Lameter2007-05-09
| | | | | | | | | | | | | | | | | CONFIG_SLUB_DEBUG can be used to switch off the debugging and sysfs components of SLUB. Thus SLUB will be able to replace SLOB. SLUB can arrange objects in a denser way than SLOB and the code size should be minimal without debugging and sysfs support. Note that CONFIG_SLUB_DEBUG is materially different from CONFIG_SLAB_DEBUG. CONFIG_SLAB_DEBUG is used to enable slab debugging in SLAB. SLUB enables debugging via a boot parameter. SLUB debug code should always be present. CONFIG_SLUB_DEBUG can be modified in the embedded config section.

* SLUB: add support for dynamic cacheline size determinationChristoph Lameter2007-05-09
| | | | | | | | | | | | | | | | SLUB currently assumes that the cacheline size is static. However, i386 f.e. supports dynamic cache line size determination. Use cache_line_size() instead of L1_CACHE_BYTES in the allocator. That also explains the purpose of SLAB_HWCACHE_ALIGN. So we will need to keep that one around to allow dynamic aligning of objects depending on boot determination of the cache line size.

* Documentation/i386/boot.txt: update and correctH. Peter Anvin2007-05-08
| | | | | | | | | | | | | | | | In the process of rewriting the x86 setup code, I found a number of inaccuracies and outdated recommendations in the boot protocol documentation. Revamp to make it more up to date. In particular, the common use of the heap actually requires (slightly) more than 4K of heap plus stack, which is the recommended amount in the document; currently the code compensates by being smaller than specified, but we can't assume that will be true forever. Thus, recommend that if we have a modern bzImage kernel, that the bootloader maximizes the available space. Signed-off-by: H.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Do not use IRQF_SHARED, these interrupt numbers should all be unique. Also use name strings without spaces in them just like PCI controller drivers do, for consistency. Signed-off-by: David S. Miller <davem@davemloft.net>
| * | [SPARC64] PCI: Use root list of pbm's instead of pci_controller_info'sDavid S. Miller2007-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The idea is to move more and more things into the pbm, with the eventual goal of eliminating the pci_controller_info entirely as there really isn't any need for it. This stage of the transformations requires some reworking of the PCI error interrupt handling. It might be tricky to get rid of the pci_controller_info parenting for a few reasons: 1) When we get an uncorrectable or correctable error we want to interrogate the IOMMU and streaming cache of both PBMs for error status. These errors come from the UPA front-end which is shared between the two PBM PCI bus segments. Historically speaking this is why I choose the datastructure hierarchy of pci_controller_info-->pci_pbm_info 2) The probing does a portid/devhandle match to look for the 'other' pbm, but this is entirely an artifact and can be eliminated trivially. What we could do to solve #1 is to have a "buddy" pointer from one pbm to another. Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Namely bus-range and ino-bitmap. This allows us also to eliminate pci_controller_info's pci_{first,last}_busno fields as only the pbm ones are used now. Signed-off-by: David S. Miller <davem@davemloft.net>
