The warning is false positive as\nof-\u003emutex is per open-file and the two paths belong to two different\nfiles.  This warning didn\u0027t trigger before regular and bin file\nsupports were merged because only bin file supported mmap and the\nother side of locking happened only on regular files which used\nequivalent but separate locking.\n\nIt\u0027d be best if we give separate locking classes per file but we can\u0027t\neasily do that.  Let\u0027s differentiate on -\u003emmap() for now.  Later we\u0027ll\nadd explicit file operations struct and can add per-ops lockdep key\nthere.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nReported-by: Dave Jones \u003cdavej@redhat.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\n"

In doing\nso it mixed a lot of single-threaded implementation specific\naspects into the decompressor code and elsewhere which makes it\ndifficult to seamlessly support multiple different decompressor\nimplementations.\n\nThis patch does the following:\n\n1.  It removes compressor_options parsing from the decompressor\n    init() function.  This allows the decompressor init() function\n    to be dynamically called to instantiate multiple decompressors,\n    without the compressor options needing to be read and parsed each\n    time.\n\n2.  It moves threading and all sleeping operations out of the\n    decompressors.  In doing so, it makes the decompressors\n    non-blocking wrappers which only deal with interfacing with\n    the decompressor implementation.\n\n3. It splits decompressor.[ch] into decompressor generic functions\n   in decompressor.[ch], and moves the single threaded\n   decompressor implementation into decompressor_single.c.\n\nThe result of this patch is Squashfs should now be able to\nsupport multiple decompressors by adding new decompressor_xxx.c\nfiles with specialised implementations of the functions in\ndecompressor_single.c\n\nSigned-off-by: Phillip Lougher \u003cphillip@squashfs.org.uk\u003e\nReviewed-by: Minchan Kim \u003cminchan@kernel.org\u003e\n"

      "message": "Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net\n\nPull networking fixes from David Miller:\n \"Mostly these are fixes for fallout due to merge window changes, as\n  well as cures for problems that have been with us for a much longer\n  period of time\"\n\n 1) Johannes Berg noticed two major deficiencies in our genetlink\n    registration.  Some genetlink protocols we passing in constant\n    counts for their ops array rather than something like\n    ARRAY_SIZE(ops) or similar.  Also, some genetlink protocols were\n    using fixed IDs for their multicast groups.\n\n    We have to retain these fixed IDs to keep existing userland tools\n    working, but reserve them so that other multicast groups used by\n    other protocols can not possibly conflict.\n\n    In dealing with these two problems, we actually now use less state\n    management for genetlink operations and multicast groups.\n\n 2) When configuring interface hardware timestamping, fix several\n    drivers that simply do not validate that the hwtstamp_config value\n    is one the driver actually supports.  From Ben Hutchings.\n\n 3) Invalid memory references in mwifiex driver, from Amitkumar Karwar.\n\n 4) In dev_forward_skb(), set the skb-\u003eprotocol in the right order\n    relative to skb_scrub_packet().  From Alexei Starovoitov.\n\n 5) Bridge erroneously fails to use the proper wrapper functions to make\n    calls to netdev_ops-\u003endo_vlan_rx_{add,kill}_vid.  Fix from Toshiaki\n    Makita.\n\n 6) When detaching a bridge port, make sure to flush all VLAN IDs to\n    prevent them from leaking, also from Toshiaki Makita.\n\n 7) Put in a compromise for TCP Small Queues so that deep queued devices\n    that delay TX reclaim non-trivially don\u0027t have such a performance\n    decrease.  One particularly problematic area is 802.11 AMPDU in\n    wireless.  From Eric Dumazet.\n\n 8) Fix crashes in tcp_fastopen_cache_get(), we can see NULL socket dsts\n    here.  Fix from Eric Dumzaet, reported by Dave Jones.\n\n 9) Fix use after free in ipv6 SIT driver, from Willem de Bruijn.\n\n10) When computing mergeable buffer sizes, virtio-net fails to take the\n    virtio-net header into account.  From Michael Dalton.\n\n11) Fix seqlock deadlock in ip4_datagram_connect() wrt.  statistic\n    bumping, this one has been with us for a while.  From Eric Dumazet.\n\n12) Fix NULL deref in the new TIPC fragmentation handling, from Erik\n    Hugne.\n\n13) 6lowpan bit used for traffic classification was wrong, from Jukka\n    Rissanen.\n\n14) macvlan has the same issue as normal vlans did wrt.  propagating LRO\n    disabling down to the real device, fix it the same way.  From Michal\n    Kubecek.\n\n15) CPSW driver needs to soft reset all slaves during suspend, from\n    Daniel Mack.\n\n16) Fix small frame pacing in FQ packet scheduler, from Eric Dumazet.\n\n17) The xen-netfront RX buffer refill timer isn\u0027t properly scheduled on\n    partial RX allocation success, from Ma JieYue.\n\n18) When ipv6 ping protocol support was added, the AF_INET6 protocol\n    initialization cleanup path on failure was borked a little.  Fix\n    from Vlad Yasevich.\n\n19) If a socket disconnects during a read/recvmsg/recvfrom/etc that\n    blocks we can do the wrong thing with the msg_name we write back to\n    userspace.  From Hannes Frederic Sowa.  There is another fix in the\n    works from Hannes which will prevent future problems of this nature.\n\n20) Fix route leak in VTI tunnel transmit, from Fan Du.\n\n* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (106 commits)\n  genetlink: make multicast groups const, prevent abuse\n  genetlink: pass family to functions using groups\n  genetlink: add and use genl_set_err()\n  genetlink: remove family pointer from genl_multicast_group\n  genetlink: remove genl_unregister_mc_group()\n  hsr: don\u0027t call genl_unregister_mc_group()\n  quota/genetlink: use proper genetlink multicast APIs\n  drop_monitor/genetlink: use proper genetlink multicast APIs\n  genetlink: only pass array to genl_register_family_with_ops()\n  tcp: don\u0027t update snd_nxt, when a socket is switched from repair mode\n  atm: idt77252: fix dev refcnt leak\n  xfrm: Release dst if this dst is improper for vti tunnel\n  netlink: fix documentation typo in netlink_set_err()\n  be2net: Delete secondary unicast MAC addresses during be_close\n  be2net: Fix unconditional enabling of Rx interface options\n  net, virtio_net: replace the magic value\n  ping: prevent NULL pointer dereference on write to msg_name\n  bnx2x: Prevent \"timeout waiting for state X\"\n  bnx2x: prevent CFC attention\n  bnx2x: Prevent panic during DMAE timeout\n  ...\n"

      "message": "xfs: open code inc_inode_iversion when logging an inode\n\nMichael L Semon reported that generic/069 runtime increased on v5\nsuperblocks by 100% compared to v4 superblocks. his perf-based\nanalysis pointed directly at the timestamp updates being done by the\nwrite path in this workload. The append writers are doing 4-byte\nwrites, so there are lots of timestamp updates occurring.\n\nThe thing is, they aren\u0027t being triggered by timestamp changes -\nthey are being triggered by the inode change counter needing to be\nupdated. That is, every write(2) system call needs to bump the inode\nversion count, and it does that through the timestamp update\nmechanism. Hence for v5 filesystems, test generic/069 is running 3\norders of magnitude more timestmap update transactions on v5\nfilesystems due to the fact it does a huge number of *4 byte*\nwrite(2) calls.\n\nThis isn\u0027t a real world scenario we really need to address - anyone\ndoing such sequential IO should be using fwrite(3), not write(2).\ni.e. fwrite(3) buffers the writes in userspace to minimise the\nnumber of write(2) syscalls, and the problem goes away.\n\nHowever, there is a small change we can make to improve the\nsituation - removing the expensive lock operation on the change\ncounter update.  All inode version counter changes in XFS occur\nunder the ip-\u003ei_ilock during a transaction, and therefore we\ndon\u0027t actually need the spin lock that provides exclusive access to\nit through inc_inode_iversion().\n\nHence avoid the lock and just open code the increment ourselves when\nlogging the inode.\n\nReported-by: Michael L.

For v5 fielsystems, scale the inode cluster size\nwith the size of the inode so that we keep a constant 32 inodes per\ncluster ratio for all inode IO.\n\nThis only works if mkfs.xfs sets the inode alignment appropriately\nfor larger inode clusters, so this functionality is made conditional\non mkfs doing the right thing. xfs_repair needs to know about\nthe inode alignment changes, too.\n\nWall time:\n\tcreate\tbulkstat\tfind+stat\tls -R\tunlink\nv4\t237s\t161s\t\t173s\t\t201s\t299s\nv5\t235s\t163s\t\t205s\t\t 31s\t356s\npatched\t234s\t160s\t\t182s\t\t 29s\t317s\n\nSystem time:\n\tcreate\tbulkstat\tfind+stat\tls -R\tunlink\nv4\t2601s\t2490s\t\t1653s\t\t1656s\t2960s\nv5\t2637s\t2497s\t\t1681s\t\t  20s\t3216s\npatched\t2613s\t2451s\t\t1658s\t\t  20s\t3007s\n\nSo, wall time same or down across the board, system time same or\ndown across the board, and cache hit rates all improve except for\nthe ls -R case which is a pure cold cache directory read workload\non v5 filesystems...\n\nSo, this patch removes most of the performance and CPU usage\ndifferential between v4 and v5 filesystems on traversal related\nworkloads.\n\nNote: while this patch is currently for v5 filesystems only, there\nis no reason it can\u0027t be ported back to v4 filesystems.  This hasn\u0027t\nbeen done here because bringing the code back to v4 requires\nforwards and backwards kernel compatibility testing.  i.e. to\ndeterine if older kernels(*) do the right thing with larger inode\nalignments but still only using 8k inode cluster sizes. None of this\ntesting and validation on v4 filesystems has been done, so for the\nmoment larger inode clusters is limited to v5 superblocks.\n\n(*) a current default config v4 filesystem should mount just fine on\n2.6.23 (when lazy-count support was introduced), and so if we change\nthe alignment emitted by mkfs without a feature bit then we have to\nmake sure it works properly on all kernels since 2.6.23. And if we\nallow it to be changed when the lazy-count bit is not set, then it\u0027s\nall kernels since v2 logs were introduced that need to be tested for\ncompatibility...\n\nSigned-off-by: Dave Chinner \u003cdchinner@redhat.com\u003e\nReviewed-by: Christoph Hellwig \u003chch@lst.de\u003e\nReviewed-by: Eric Sandeen \u003csandeen@redhat.com\u003e\nSigned-off-by: Ben Myers \u003cbpm@sgi.com\u003e\n\n"

Hence change its type from\nsize_t to u16, and use do_div() to perform a 64-by-32 division.\n\nNot seen in m68k/allmodconfig in -next, so it really depends on the\nverion of gcc.\n\nSigned-off-by: Geert Uytterhoeven \u003cgeert@linux-m68k.org\u003e\nCc: Vyacheslav Dubeyko \u003cslava@dubeyko.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"
