      Btrfs: allow metadata blocks larger than the page size · 727011e0
      Chris Mason 提交于
      A few years ago the btrfs code to support blocks lager than
      the page size was disabled to fix a few corner cases in the
      page cache handling.  This fixes the code to properly support
      large metadata blocks again.
      
      Since current kernels will crash early and often with larger
      metadata blocks, this adds an incompat bit so that older kernels
      can't mount it.
      
      This also does away with different blocksizes for nodes and leaves.
      You get a single block size for all tree blocks.

      Btrfs: remove search_start and search_end from find_free_extent and callers · 81c9ad23
      Josef Bacik 提交于
      We have been passing nothing but (u64)-1 to find_free_extent for search_end in
      all of the callers, so it's completely useless, and we've always been passing 0
      in as search_start, so just remove them as function arguments and move
      search_start into find_free_extent.  Thanks,

      Btrfs: remove the ideal caching code · 285ff5af
      Josef Bacik 提交于
      This is a relic from before we had the disk space cache and it was to make
      bootup times when you had btrfs as root not be so damned slow.  Now that we have
      the disk space cache this isn't a problem anymore and really having this code
      casues uneeded fragmentation and complexity, so just remove it.  Thanks,

      Pull networking changes from David Miller:
       "1) icmp6_dst_alloc() returns NULL instead of ERR_PTR() leading to
           crashes, particularly during shutdown.  Reported by Dave Jones and
           fixed by Eric Dumazet.
      
        2) hyperv and wimax/i2400m return NETDEV_TX_BUSY when they have
           already freed the SKB, which causes crashes as to the caller this
           means requeue the packet.  Fixes from Eric Dumazet.
      
        3) usbnet driver doesn't allocate the right amount of headroom on
           fresh RX SKBs, fix from Eric Dumazet.
      
        4) Fix regression in ip6_mc_find_dev_rcu(), as an RCU lookup it
           abolutely should not take a reference to 'dev', this leads to
           leaks.  Fix from RonQing Li.
      
        5) Fix netfilter ctnetlink race between delete and timeout expiration.
           From Pablo Neira Ayuso.
      
        6) Revert SFQ change which causes regressions, specifically queueing
           to tail can lead to unavoidable flow starvation.  From Eric
           Dumazet.
      
        7) Fix a memory leak and a crash on corrupt firmware files in bnx2x,
           from Michal Schmidt."
