In\nsome cases up to 32K. However simply setting MSGMNI to a larger value may\ncause problems for smaller systems.\n\nThe first patch of this series introduces a default maximum number of message\nqueue ids that scales with the amount of lowmem.\n\nSince msgmni is per namespace and there is no amount of memory dedicated to\neach namespace so far, the second patch of this series scales msgmni to the\nnumber of ipc namespaces too.\n\nSince msgmni depends on the amount of memory, it becomes necessary to\nrecompute it upon memory add/remove. In the 4th patch, memory hotplug\nmanagement is added: a notifier block is registered into the memory hotplug\nnotifier chain for the ipc subsystem. Since the ipc namespaces are not linked\ntogether, they have their own notification chain: one notifier_block is\ndefined per ipc namespace. Each time an ipc namespace is created (removed) it\nregisters (unregisters) its notifier block in (from) the ipcns chain. The\ncallback routine registered in the memory chain invokes the ipcns notifier\nchain with the IPCNS_MEMCHANGE event. Each callback routine registered in the\nipcns namespace, in turn, recomputes msgmni for the owning namespace.\n\nThe 5th patch makes it possible to keep the memory hotplug notifier chain\u0027s\nlock for a lesser amount of time: instead of directly notifying the ipcns\nnotifier chain upon memory add/remove, a work item is added to the global\nworkqueue. When activated, this work item is the one who notifies the ipcns\nnotifier chain.\n\nSince msgmni depends on the number of ipc namespaces, it becomes necessary to\nrecompute it upon ipc namespace creation / removal. The 6th patch uses the\nipc namespace notifier chain for that purpose: that chain is notified each\ntime an ipc namespace is created or removed. This makes it possible to\nrecompute msgmni for all the namespaces each time one of them is created or\nremoved.\n\nWhen msgmni is explicitely set from userspace, we should avoid recomputing it\nupon memory add/remove or ipcns creation/removal. This is what the 7th patch\ndoes: it simply unregisters the ipcns callback routine as soon as msgmni has\nbeen changed from procfs or sysctl().\n\nEven if msgmni is set by hand, it should be possible to make it back\nautomatically recomputed upon memory add/remove or ipcns creation/removal.\nThis what is achieved in patch 8: if set to a negative value, msgmni is added\nback to the ipcns notifier chain, making it automatically recomputed again.\n\nThis patch:\n\nCompute msg_ctlmni to make it scale with the amount of lowmem. msg_ctlmni is\nnow set to make the message queues occupy 1/32 of the available lowmem.\n\nSome cleaning has also been done for the MSGPOOL constant: the msgctl man page\nsays it\u0027s not used, but it also defines it as a size in bytes (the code\nexpresses it in Kbytes).\n\nSigned-off-by: Nadia Derbey \u003cNadia.Derbey@bull.net\u003e\nCc: Yasunori Goto \u003cy-goto@jp.fujitsu.com\u003e\nCc: Matt Helsley \u003cmatthltc@us.ibm.com\u003e\nCc: Mingming Cao \u003ccmm@us.ibm.com\u003e\nCc: Pierre Peiffer \u003cpierre.peiffer@bull.net\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "74bc7ceebfa1c84ddd3a843ebfb56df013bf7ef5", "tree": "548155250fbc7410273125019c70a7c5c085e895", "parents": [ "d2ba7e2ae206e9ab24e8937d99d0d5513bfd08e5" ], "author": { "name": "Arthur Kepner", "email": "akepner@sgi.com", "time": "Tue Apr 29 01:00:30 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Apr 29 08:06:11 2008 -0700" }, "message": "dma: add dma_*map*_attrs() interfaces\n\nIntroduce new interfaces, dma_*map*_attrs(), for passing architecture-specific\nattributes when memory is mapped and unmapped for DMA.

Further, many\napplications exist that may never get upgraded in this way, and the kernel\nwill continue to want to support their setuid-0 base privilege needs.\n\nWhere pure-capability applications evolve and replace setuid-0 binaries, it is\ndesirable that there be a mechanisms by which they can contain their\nprivilege.

Because the section has to be\n logical memory offlined already and all pages must be isolated against\n page allocater. If it is freed, page allocator may use it which will\n be removed physically soon.\n 3) When removing section has other section\u0027s memmap,\n kernel will be able to show easily which section should be removed\n before it for user. (Not implemented yet)\n 4) When the above case 2), the page isolation will be able to check and skip\n memmap\u0027s page when logical memory offline (offline_pages()).\n Current page isolation code fails in this case because this page is\n just reserved page and it can\u0027t distinguish this pages can be\n removed or not.

For MPOL_DEFAULT, the\nreturned pointer is NULL. Further, mpol_parse_str() now takes a \u0027no_context\u0027\nargument that causes the input nodemask to be stored in the w.user_nodemask of\nthe created mempolicy for use when the mempolicy is installed in a tmpfs inode\nshared policy tree. At that time, any cpuset contextualization is applied to\nthe original input nodemask. This preserves the previous behavior where the\ninput nodemask was stored in the superblock. We can think of the returned\nmempolicy as \"context free\".\n\nBecause mpol_parse_str() is now calling mpol_new(), we can remove from\nmpol_to_str() the semantic checks that mpol_new() already performs.\n\nAdd \u0027no_context\u0027 parameter to mpol_to_str() to specify that it should format\nthe nodemask in w.user_nodemask for \u0027bind\u0027 and \u0027interleave\u0027 policies.\n\nChange mpol_shared_policy_init() to take a pointer to a \"context free\" struct\nmempolicy and to create a new, \"contextualized\" mempolicy using the mode,\nmode_flags and user_nodemask from the input mempolicy.\n\n Note: we know that the mempolicy passed to mpol_to_str() or\n mpol_shared_policy_init() from a tmpfs superblock is \"context free\". This\n is currently the only instance thereof. However, if we found more uses for\n this concept, and introduced any ambiguity as to whether a mempolicy was\n context free or not, we could add another internal mode flag to identify\n context free mempolicies. Then, we could remove the \u0027no_context\u0027 argument\n from mpol_to_str().\n\nAdded shmem_get_sbmpol() to return a reference counted superblock mempolicy,\nif one exists, to pass to mpol_shared_policy_init().

In other areas, further inspection reveals that I botched the\nunref for interleave policies.\n\nA separate patch, suitable for upstream/stable trees, fixes up the known\nerrors in the previous attempt to fix reference counting.\n\nThis patch reworks the memory policy referencing counting and, one hopes,\nsimplifies the code. Maybe I\u0027ll get it right this time.\n\nSee the update to the numa_memory_policy.txt document for a discussion of\nmemory policy reference counting that motivates this patch.\n\nSummary:\n\nLookup of mempolicy, based on (vma, address) need only add a reference for\nshared policy, and we need only unref the policy when finished for shared\npolicies. So, this patch backs out all of the unneeded extra reference\ncounting added by my previous attempt. It then unrefs only shared policies\nwhen we\u0027re finished with them, using the mpol_cond_put() [conditional put]\nhelper function introduced by this patch.\n\nNote that shmem_swapin() calls read_swap_cache_async() with a dummy vma\ncontaining just the policy. read_swap_cache_async() can call alloc_page_vma()\nmultiple times, so we can\u0027t let alloc_page_vma() unref the shared policy in\nthis case. To avoid this, we make a copy of any non-null shared policy and\nremove the MPOL_F_SHARED flag from the copy. This copy occurs before reading\na page [or multiple pages] from swap, so the overhead should not be an issue\nhere.\n\nI introduced a new static inline function \"mpol_cond_copy()\" to copy the\nshared policy to an on-stack policy and remove the flags that would require a\nconditional free. The current implementation of mpol_cond_copy() assumes that\nthe struct mempolicy contains no pointers to dynamically allocated structures\nthat must be duplicated or reference counted during copy.\n\nSigned-off-by: Lee Schermerhorn \u003clee.schermerhorn@hp.com\u003e\nCc: Christoph Lameter \u003cclameter@sgi.com\u003e\nCc: David Rientjes \u003crientjes@google.com\u003e\nCc: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: Andi Kleen \u003cak@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "a6020ed759404372e8be2b276e85e51735472cc9", "tree": "1fb0a346909dcc9d3b916671001af87b17931ddd", "parents": [ "aab0b1029f0843756b68e0ed3ca983685bf43ed6" ], "author": { "name": "Lee Schermerhorn", "email": "lee.schermerhorn@hp.com", "time": "Mon Apr 28 02:13:14 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Apr 28 08:58:24 2008 -0700" }, "message": "mempolicy: document {set|get}_policy() vm_ops APIs\n\nDocument mempolicy return value reference semantics assumed by the rest of the\nmempolicy code for the set_ and get_policy vm_ops in \u003clinux/mm.h\u003e--where the\nprototypes are defined--to inform any future mempolicy vm_op writers what the\nrest of the subsystem expects of them.\n\nSigned-off-by: Lee Schermerhorn \u003clee.schermerhorn@hp.com\u003e\nCc: Christoph Lameter \u003cclameter@sgi.com\u003e\nCc: David Rientjes \u003crientjes@google.com\u003e\nCc: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: Andi Kleen \u003cak@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" } ], "next": "aab0b1029f0843756b68e0ed3ca983685bf43ed6" }
