      "message": "dm kcopyd: fix callback race\n\nIf the thread calling dm_kcopyd_copy is delayed due to scheduling inside\nsplit_job/segment_complete and the subjobs complete before the loop in\nsplit_job completes, the kcopyd callback could be invoked from the\nthread that called dm_kcopyd_copy instead of the kcopyd workqueue.\n\ndm_kcopyd_copy -\u003e split_job -\u003e segment_complete -\u003e job-\u003efn()\n\nSnapshots depend on the fact that callbacks are called from the singlethreaded\nkcopyd workqueue and expect that there is no racing between individual\ncallbacks. The racing between callbacks can lead to corruption of exception\nstore and it can also mean that exception store callbacks are called twice\nfor the same exception - a likely reason for crashes reported inside\npending_complete() / remove_exception().\n\nThis patch fixes two problems:\n\n1. job-\u003efn being called from the thread that submitted the job (see above).\n\n- Fix: hand over the completion callback to the kcopyd thread.\n\n2. job-\u003efn(read_err, write_err, job-\u003econtext); in segment_complete\nreports the error of the last subjob, not the union of all errors.\n\n- Fix: pass job-\u003ewrite_err to the callback to report all error bits\n  (it is done already in run_complete_job)\n\nCc: stable@kernel.org\nSigned-off-by: Mikulas Patocka \u003cmpatocka@redhat.com\u003e\nSigned-off-by: Alasdair G Kergon \u003cagk@redhat.com\u003e\n"

(We must wait, otherwise it could be intermixed with\nfollowing requests.)\n\nErrors from the barrier request are recorded in a per-device barrier_error\nvariable. There may be only one barrier request in progress at once.\n\nFor now, the barrier request is converted to a non-barrier request when\nsending it to the underlying device.\n\nThis patch guarantees correct barrier behavior if the underlying device\ndoesn\u0027t perform write-back caching. The same requirement existed before\nbarriers were supported in dm.\n\nBottom layer barrier support (sending barriers by target drivers) and\nhandling devices with write-back caches will be done in further patches.\n\nSigned-off-by: Mikulas Patocka \u003cmpatocka@redhat.com\u003e\nSigned-off-by: Alasdair G Kergon \u003cagk@redhat.com\u003e\n"

      "message": "nilfs2: buffer and page operations\n\nThis adds common routines for buffer/page operations used in B-tree\nnode caches, meta data files, or segment constructor (log writer).\n\nNILFS uses copy functions for buffers and pages due to the following\nreasons:\n\n 1) Relocation required for COW\n    Since NILFS changes address of on-disk blocks, moving buffers\n    in page cache is needed for the buffers which are not addressed\n    by a file offset.  If buffer size is smaller than page size,\n    this involves partial copy of pages.\n\n 2) Freezing mmapped pages\n    NILFS calculates checksums for each log to ensure its validity.\n    If page data changes after the checksum calculation, this validity\n    check will not work correctly.  To avoid this failure for mmaped\n    pages, NILFS freezes their data by copying.\n\n 3) Copy-on-write for DAT pages\n    NILFS makes clones of DAT page caches in a copy-on-write manner\n    during GC processes, and this ensures atomicity and consistency\n    of the DAT in the transient state.\n\nIn addition, NILFS uses two obsolete functions, nilfs_mark_buffer_dirty()\nand nilfs_clear_page_dirty() respectively.\n\n* nilfs_mark_buffer_dirty() was required to avoid NULL pointer\n  dereference faults:\n\n  Since the page cache of B-tree node pages or data page cache of pseudo\n  inodes does not have a valid mapping-\u003ehost, calling mark_buffer_dirty()\n  for their buffers causes the fault; it calls __mark_inode_dirty(NULL)\n  through __set_page_dirty().\n\n* nilfs_clear_page_dirty() was needed in the two cases:\n\n 1) For B-tree node pages and data pages of the dat/gcdat, NILFS2 clears\n    page dirty flags when it copies back pages from the cloned cache\n    (gcdat-\u003e{i_mapping,i_btnode_cache}) to its original cache\n    (dat-\u003e{i_mapping,i_btnode_cache}).\n\n 2) Some B-tree operations like insertion or deletion may dispose buffers\n    in dirty state, and this needs to cancel the dirty state of their\n    pages.  clear_page_dirty_for_io() caused faults because it does not\n    clear the dirty tag on the page cache.\n\nSigned-off-by: Seiji Kihara \u003ckihara.seiji@lab.ntt.co.jp\u003e\nSigned-off-by: Ryusuke Konishi \u003ckonishi.ryusuke@lab.ntt.co.jp\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "namespaces: ipc namespaces: implement support for posix msqueues\n\nImplement multiple mounts of the mqueue file system, and link it to usage\nof CLONE_NEWIPC.\n\nEach ipc ns has a corresponding mqueuefs superblock.  When a user does\nclone(CLONE_NEWIPC) or unshare(CLONE_NEWIPC), the unshare will cause an\ninternal mount of a new mqueuefs sb linked to the new ipc ns.\n\nWhen a user does \u0027mount -t mqueue mqueue /dev/mqueue\u0027, he mounts the\nmqueuefs superblock.\n\nPosix message queues can be worked with both through the mq_* system calls\n(see mq_overview(7)), and through the VFS through the mqueue mount.  Any\nusage of mq_open() and friends will work with the acting task\u0027s ipc\nnamespace.  Any actions through the VFS will work with the mqueuefs in\nwhich the file was created.  So if a user doesn\u0027t remount mqueuefs after\nunshare(CLONE_NEWIPC), mq_open(\"/ab\") will not be reflected in \"ls\n/dev/mqueue\".\n\nIf task a mounts mqueue for ipc_ns:1, then clones task b with a new ipcns,\nipcns:2, and then task a is the last task in ipc_ns:1 to exit, then (1)\nipc_ns:1 will be freed, (2) it\u0027s superblock will live on until task b\numounts the corresponding mqueuefs, and vfs actions will continue to\nsucceed, but (3) sb-\u003es_fs_info will be NULL for the sb corresponding to\nthe deceased ipc_ns:1.\n\nTo make this happen, we must protect the ipc reference count when\n\na) a task exits and drops its ipcns-\u003ecount, since it might be dropping\n   it to 0 and freeing the ipcns\n\nb) a task accesses the ipcns through its mqueuefs interface, since it\n   bumps the ipcns refcount and might race with the last task in the ipcns\n   exiting.\n\nSo the kref is changed to an atomic_t so we can use\natomic_dec_and_lock(\u0026ns-\u003ecount,mq_lock), and every access to the ipcns\nthrough ns \u003d mqueuefs_sb-\u003es_fs_info is protected by the same lock.\n\nSigned-off-by: Cedric Le Goater \u003cclg@fr.ibm.com\u003e\nSigned-off-by: Serge E.
