This new VMA is a direct copy of the original\nincluding the reservation count. When this pair of VMAs are unmapped we\nwill incorrect double account the unused reservation and the overall\nreservation count will be incorrect, in extreme cases it will wrap.\n\nThe problem occurs when we split an existing VMA say to unmap a page in\nthe middle. split_vma() will create a new VMA copying all fields from the\noriginal. As we are storing our reservation count in vm_private_data this\nis also copies, endowing the new VMA with a duplicate of the original\nVMA\u0027s reservation. Neither of the new VMAs can exhaust these reservations\nas they are too small, but when we unmap and close these VMAs we will\nincorrect credit the remainder twice and resv_huge_pages will become out\nof sync. This can lead to allocation failures on mappings with\nreservations and even to resv_huge_pages wrapping which prevents all\nsubsequent hugepage allocations.\n\nThe simple fix would be to correctly apportion the remaining reservation\ncount when the split is made. However the only hook we have vm_ops-\u003eopen\nonly has the new VMA we do not know the identity of the preceeding VMA.\nAlso even if we did have that VMA to hand we do not know how much of the\nreservation was consumed each side of the split.\n\nThis patch therefore takes a different tack. We know that the whole of\nany private mapping (which has a reservation) has a reservation over its\nwhole size. Any present pages represent consumed reservation. Therefore\nif we track the instantiated pages we can calculate the remaining\nreservation.\n\nThis patch reuses the existing regions code to track the regions for which\nwe have consumed reservation (ie. the instantiated pages), as each page\nis faulted in we record the consumption of reservation for the new page.\nWhen we need to return unused reservations at unmap time we simply count\nthe consumed reservation region subtracting that from the whole of the\nmap. During a VMA split the newly opened VMA will point to the same\nregion map, as this map is offset oriented it remains valid for both of\nthe split VMAs. This map is referenced counted so that it is removed when\nall VMAs which are part of the mmap are gone.\n\nThanks to Adam Litke and Mel Gorman for their review feedback.\n\nSigned-off-by: Andy Whitcroft \u003capw@shadowen.org\u003e\nAcked-by: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: Adam Litke \u003cagl@us.ibm.com\u003e\nCc: Johannes Weiner \u003channes@saeurebad.de\u003e\nCc: Andy Whitcroft \u003capw@shadowen.org\u003e\nCc: William Lee Irwin III \u003cwli@holomorphy.com\u003e\nCc: Hugh Dickins \u003chugh@veritas.com\u003e\nCc: Michael Kerrisk \u003cmtk.manpages@googlemail.com\u003e\nCc: Jon Tollefson \u003ckniht@linux.vnet.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "c37f9fb11c976ffc08200d631dada6dcbfd07ea4", "tree": "2598f0713e4e61ed90335db1745decf2da6086a4", "parents": [ "9682290484370ce68ba23cd2ec2838e301934199" ], "author": { "name": "Andy Whitcroft", "email": "apw@shadowen.org", "time": "Wed Jul 23 21:27:30 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Jul 24 10:47:16 2008 -0700" }, "message": "hugetlb: allow huge page mappings to be created without reservations\n\nBy default all shared mappings and most private mappings now have\nreservations associated with them.

If the child performs COW first, it will attempt to satisfy the COW\n from the pool if there are enough pages or via the buddy allocator if\n overcommit is allowed and the buddy allocator can satisfy the request. If\n it fails, the child will be killed.\n\nIf the pool is large enough, existing applications will not notice that\nthe reserves were a factor.

However\nthere are a number of bits which are overloaded by different subsystems.\nFirstly there is PG_owner_priv_1 which is used by filesystems and by XEN.\nSecondly both SLOB and SLUB use a couple of extra page bits to manage\ninternal state for pages they own; both overlay other bits. All of these\n\"aliases\" are scattered about the source making it very hard for a reader\nto know if the bits are safe to rely on in all contexts; confusion here is\nbad.\n\nAs we now have a single place where the bits are clearly assigned it makes\nsense to clarify the reuse of bits by making the aliases explicit and\nvisible with the original bit assignments. This patch creates explicit\naliases within the enum itself for the overloaded bits, creates standard\nbit accessors PageFoo etc. and uses those throughout.\n\nThis version pulls the bit manipulation out to standard named page bit\naccessors as suggested by Christoph, it retains the explicit mapping to\nthe overlayed bits. A fusion of both ideas. This has been SLUB and SLOB\nhave been compile tested on x86_64 only, and SLUB boot tested. If people\nfeel this is worth doing then I can run a fuller set of testing.\n\nThis patch:\n\nSome page flags are used for more than one purpose, for example\nPG_owner_priv_1. Currently there are individual accessors for each user,\neach built using the common flag name far away from the bit definitions.\nThis makes it hard to see all possible uses of these bits.\n\nNow that we have a single enum to generate the bit orders it makes sense\nto express overlays in the same place. So create per use aliases for this\nbit in the main page-flags enum and use those in the accessors.\n\n[akpm@linux-foundation.org: fix xen]\nSigned-off-by: Andy Whitcroft \u003capw@shadowen.org\u003e\nCc: Pekka Enberg \u003cpenberg@cs.helsinki.fi\u003e\nCc: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Matt Mackall \u003cmpm@selenic.com\u003e\nCc: Nick Piggin \u003cnickpiggin@yahoo.com.au\u003e\nCc: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nReviewed-by: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Rik van Riel \u003criel@redhat.com\u003e\nCc: Jeremy Fitzhardinge \u003cjeremy@goop.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "da3bbdd4632c0171406b2677e31494afa5bde2f8", "tree": "6a1947b2a32041ef0d14044e659ba7d546d55483", "parents": [ "3c82d0ce2c4f642b2f24ef98707a030543b06b90" ], "author": { "name": "Kentaro Makita", "email": "k-makita@np.css.fujitsu.com", "time": "Wed Jul 23 21:27:13 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Jul 24 10:47:15 2008 -0700" }, "message": "fix soft lock up at NFS mount via per-SB LRU-list of unused dentries\n\n[Summary]\n\n Split LRU-list of unused dentries to one per superblock to avoid soft\n lock up during NFS mounts and remounting of any filesystem.\n\n Previously I posted here:\n http://lkml.org/lkml/2008/3/5/590\n\n[Descriptions]\n\n- background\n\n dentry_unused is a list of dentries which are not referenced.\n dentry_unused grows up when references on directories or files are\n released. This list can be very long if there is huge free memory.\n\n- the problem\n\n When shrink_dcache_sb() is called, it scans all dentry_unused linearly\n under spin_lock(), and if dentry-\u003ed_sb is differnt from given\n superblock, scan next dentry. This scan costs very much if there are\n many entries, and very ineffective if there are many superblocks.\n\n IOW, When we need to shrink unused dentries on one dentry, but scans\n unused dentries on all superblocks in the system. For example, we scan\n 500 dentries to unmount a filesystem, but scans 1,000,000 or more unused\n dentries on other superblocks.\n\n In our case , At mounting NFS*, shrink_dcache_sb() is called to shrink\n unused dentries on NFS, but scans 100,000,000 unused dentries on\n superblocks in the system such as local ext3 filesystems. I hear NFS\n mounting took 1 min on some system in use.\n\n* : NFS uses virtual filesystem in rpc layer, so NFS is affected by\n this problem.\n\n 100,000,000 is possible number on large systems.\n\n Per-superblock LRU of unused dentried can reduce the cost in\n reasonable manner.\n\n- How to fix\n\n I found this problem is solved by David Chinner\u0027s \"Per-superblock\n unused dentry LRU lists V3\"(1), so I rebase it and add some fix to\n reclaim with fairness, which is in Andrew Morton\u0027s comments(2).\n\n 1) http://lkml.org/lkml/2006/5/25/318\n 2) http://lkml.org/lkml/2006/5/25/320\n\n Split LRU-list of unused dentries to each superblocks. Then, NFS\n mounting will check dentries under a superblock instead of all. But\n this spliting will break LRU of dentry-unused. So, I\u0027ve attempted to\n make reclaim unused dentrins with fairness by calculate number of\n dentries to scan on this sb based on following way\n\n number of dentries to scan on this sb \u003d\n count * (number of dentries on this sb / number of dentries in the machine)\n\n- ToDo\n - I have to measuring performance number and do stress tests.\n\n - When unmount occurs during prune_dcache(), scanning on same\n superblock, It is unable to reach next superblock because it is gone\n away. We restart scannig superblock from first one, it causes\n unfairness of reclaim unused dentries on first superblock. But I think\n this happens very rarely.\n\n- Test Results\n\n Result on 6GB boxes with excessive unused dentries.\n\nWithout patch:\n\n$ cat /proc/sys/fs/dentry-state\n10181835 10180203 45 0 0 0\n# mount -t nfs 10.124.60.70:/work/kernel-src nfs\nreal 0m1.830s\nuser 0m0.001s\nsys 0m1.653s\n\n With this patch:\n$ cat /proc/sys/fs/dentry-state\n10236610 10234751 45 0 0 0\n# mount -t nfs 10.124.60.70:/work/kernel-src nfs\nreal 0m0.106s\nuser 0m0.002s\nsys 0m0.032s\n\n[akpm@linux-foundation.org: fix comments]\nSigned-off-by: Kentaro Makita \u003ck-makita@np.css.fujitsu.com\u003e\nCc: Neil Brown \u003cneilb@suse.de\u003e\nCc: Trond Myklebust \u003ctrond.myklebust@fys.uio.no\u003e\nCc: David Chinner \u003cdgc@sgi.com\u003e\nCc: \"J.
