      There are few important bug fixes for LogFS
      
      * tag 'for-linus' of git://github.com/prasad-joshi/logfs_upstream:
        Logfs: Allow NULL block_isbad() methods
        logfs: Grow inode in delete path
        logfs: Free areas before calling generic_shutdown_super()
        logfs: remove useless BUG_ON
        MAINTAINERS: Add Prasad Joshi in LogFS maintiners
        logfs: Propagate page parameter to __logfs_write_inode
        logfs: set superblock shutdown flag after generic sb shutdown
        logfs: take write mutex lock during fsync and sync
        logfs: Prevent memory corruption
        logfs: update page reference count for pined pages
      
      Fix up conflict in fs/logfs/dev_mtd.c due to semantic change in what
      "mtd->block_isbad" means in commit f2933e86: "Logfs: Allow NULL
      block_isbad() methods" clashing with the abstraction changes in the
      commits 7086c19d: "mtd: introduce mtd_block_isbad interface" and
      d58b27ed: "logfs: do not use 'mtd->block_isbad' directly".
      
      This resolution takes the semantics from commit f2933e86, and just
      makes mtd_block_isbad() return zero (false) if the 'block_isbad'
      function is NULL.  But that also means that now "mtd_can_have_bb()"
      always returns 0.
      
      Now, "mtd_block_markbad()" will obviously return an error if the
      low-level driver doesn't support bad blocks, so this is somewhat
      non-symmetric, but it actually makes sense if a NULL "block_isbad"
      function is considered to mean "I assume that all my blocks are always
      good".

      1) Setting link attributes can modify the size of the attributes that
         would be reported on a subsequent getlink netlink operation,
         therefore min_ifinfo_dump_size needs to be adjusted.  From Stefan
         Gula.
      
      2) Resegmentation of TSO frames while trimming can violate invariants
         expected by callers, namely that the number of segments can only stay
         the same or decrease, never increase.  If MSS changes, however, we
         can trim data but then end up with more segments.  Fix this by only
         segmenting to the MSS already recorded in the SKB.  That's the
         simplest fix for now and if we want to get more fancy in the future
         that's a more involved change.
      
         This probably explains some retransmit counter inaccuracies.

      af_unix: fix EPOLLET regression for stream sockets · 6f01fd6e
      Eric Dumazet 提交于
      Commit 0884d7aa (AF_UNIX: Fix poll blocking problem when reading from
      a stream socket) added a regression for epoll() in Edge Triggered mode
      (EPOLLET)
      
      Appropriate fix is to use skb_peek()/skb_unlink() instead of
      skb_dequeue(), and only call skb_unlink() when skb is fully consumed.
      
      This remove the need to requeue a partial skb into sk_receive_queue head
      and the extra sk->sk_data_ready() calls that added the regression.
      
      This is safe because once skb is given to sk_receive_queue, it is not
      modified by a writer, and readers are serialized by u->readlock mutex.
      
      This also reduce number of spinlock acquisition for small reads or
      MSG_PEEK users so should improve overall performance.

      tcp: fix tcp_trim_head() to adjust segment count with skb MSS · 5b35e1e6
      Neal Cardwell 提交于
      This commit fixes tcp_trim_head() to recalculate the number of
      segments in the skb with the skb's existing MSS, so trimming the head
      causes the skb segment count to be monotonically non-increasing - it
      should stay the same or go down, but not increase.
      
      Previously tcp_trim_head() used the current MSS of the connection. But
      if there was a decrease in MSS between original transmission and ACK
      (e.g. due to PMTUD), this could cause tcp_trim_head() to
      counter-intuitively increase the segment count when trimming bytes off
      the head of an skb. This violated assumptions in tcp_tso_acked() that
      tcp_trim_head() only decreases the packet count, so that packets_acked
      in tcp_tso_acked() could underflow, leading tcp_clean_rtx_queue() to
      pass u32 pkts_acked values as large as 0xffffffff to
      ca_ops->pkts_acked().
      
      As an aside, if tcp_trim_head() had really wanted the skb to reflect
      the current MSS, it should have called tcp_set_skb_tso_segs()
      unconditionally, since a decrease in MSS would mean that a
      single-packet skb should now be sliced into multiple segments.

      net/tcp: Fix tcp memory limits initialization when !CONFIG_SYSCTL · 4acb4190
      Glauber Costa 提交于
      sysctl_tcp_mem() initialization was moved to sysctl_tcp_ipv4.c
      in commit 3dc43e3e, since it
      became a per-ns value.
      
      That code, however, will never run when CONFIG_SYSCTL is
      disabled, leading to bogus values on those fields - causing hung
      TCP sockets.
      
      This patch fixes it by keeping an initialization code in
      tcp_init(). It will be overwritten by the first net namespace
      init if CONFIG_SYSCTL is compiled in, and do the right thing if
      it is compiled out.
      
      It is also named properly as tcp_init_mem(), to properly signal
      its non-sysctl side effect on TCP limits.

      Fix up conflict due to arch/arm/mach-mx5/Kconfig having been merged into
      mach-imx5 (commit 784a90c0: "ARM i.MX: Merge i.MX5 support into
      mach-imx"), but the ARM_L1_CACHE_SHIFT_6 entry was moved to be driven by
      the CPU_V7 logic from it in the old location in rmk's branch (commit
      a092f2b1: "ARM: 7291/1: cache: assume 64-byte L1 cachelines for
      ARMv7 CPUs").

      Linus Torvalds 提交于
      arm-soc fixes for 3.3-rc:
      
      AT91 needed reset fixes which resulted in some minor code refactoring,
      it also adds a feature-removal for one of their platforms for 3.4.
      The USB patches have been acked by Greg K-H.
      
      i.MX and ux500 both have some minor fixes, nothing controversial.
