Otherwise, \"rmmod -f\"\nmay be stuck and never return.\nAnd now, because the mapped_device is deleted at this point, subsequent\naccesses to the mapped_device may cause NULL pointer references.\n\nCc: stable@kernel.org\nSigned-off-by: Kiyoshi Ueda \u003ck-ueda@ct.jp.nec.com\u003e\nSigned-off-by: Jun\u0027ichi Nomura \u003cj-nomura@ce.jp.nec.com\u003e\nSigned-off-by: Alasdair G Kergon \u003cagk@redhat.com\u003e\n"

      "message": "dm table: rework reference counting\n\nRework table reference counting.\n\nThe existing code uses a reference counter. When the last reference is\ndropped and the counter reaches zero, the table destructor is called.\nTable reference counters are acquired/released from upcalls from other\nkernel code (dm_any_congested, dm_merge_bvec, dm_unplug_all).\nIf the reference counter reaches zero in one of the upcalls, the table\ndestructor is called from almost random kernel code.\n\nThis leads to various problems:\n* dm_any_congested being called under a spinlock, which calls the\n  destructor, which calls some sleeping function.\n* the destructor attempting to take a lock that is already taken by the\n  same process.\n* stale reference from some other kernel code keeps the table\n  constructed, which keeps some devices open, even after successful\n  return from \"dmsetup remove\". This can confuse lvm and prevent closing\n  of underlying devices or reusing device minor numbers.\n\nThe patch changes reference counting so that the table destructor can be\ncalled only at predetermined places.\n\nThe table has always exactly one reference from either mapped_device-\u003emap\nor hash_cell-\u003enew_map. After this patch, this reference is not counted\nin table-\u003eholders.  A pair of dm_create_table/dm_destroy_table functions\nis used for table creation/destruction.\n\nTemporary references from the other code increase table-\u003eholders. A pair\nof dm_table_get/dm_table_put functions is used to manipulate it.\n\nWhen the table is about to be destroyed, we wait for table-\u003eholders to\nreach 0. Then, we call the table destructor.  We use active waiting with\nmsleep(1), because the situation happens rarely (to one user in 5 years)\nand removing the device isn\u0027t performance-critical task: the user doesn\u0027t\ncare if it takes one tick more or not.\n\nThis way, the destructor is called only at specific points\n(dm_table_destroy function) and the above problems associated with lazy\ndestruction can\u0027t happen.\n\nFinally remove the temporary protection added to dm_any_congested().\n\nSigned-off-by: Mikulas Patocka \u003cmpatocka@redhat.com\u003e\nSigned-off-by: Alasdair G Kergon \u003cagk@redhat.com\u003e\n"

It may fail if a bio arrives from the\nblock layer but its target sector is no longer included in the DM\nbtree.\n\nThis patch appends an empty entry to table-\u003etargets[] which will\nbe returned by a lookup beyond the end of the device.\n\nAfter calling dm_table_find_target(), __clone_and_map() and target_message()\ncheck for this condition using\ndm_target_is_valid().\n\nSample test script to trigger oops:\n"
