       ("SLUB: Pass active
      and inactive redzone flags instead of boolean to debug functions")
      missed two instances of check_object(). This caused a lot of warnings
      during 'slabinfo -v' finally leading to a crash:
      
        BUG ext4_xattr: Freepointer corrupt
        ...
        BUG buffer_head: Freepointer corrupt
        ...

      This patch fixes the problem by converting the two missed instances.

      Btrfs: setup blank root and fs_info for mount time · 450ba0ea
      Josef Bacik authored
      
      
      There is a problem with how we use sget, it searches through the list of supers
      attached to the fs_type looking for a super with the same fs_devices as what
      we're trying to mount.  This depends on sb->s_fs_info being filled, but we don't
      fill that in until we get to btrfs_fill_super, so we could hit supers on the
      fs_type super list that have a null s_fs_info.  In order to fix that we need to
      go ahead and setup a blank root with a blank fs_info to hold fs_devices, that
      way our test will work out right and then we can set s_fs_info in
      btrfs_set_super, and then open_ctree will simply use our pre-allocated root and
      fs_info when setting everything up.  Thanks,

      Btrfs: fix fiemap · 975f84fe
      Josef Bacik authored
      
      
      There are two big problems currently with FIEMAP
      
      1) We return extents for holes.  This isn't supposed to happen, we just don't
      return extents for holes and then userspace interprets the lack of an extent as
      a hole.
      
      2) We sometimes don't set FIEMAP_EXTENT_LAST properly.  This is because we wait
      to see a EXTENT_FLAG_VACANCY flag on the em, but this won't happen if say we ask
      fiemap to map up to the last extent in a file, and there is nothing but holes up
      to the i_size.  To fix this we need to lookup the last extent in this file and
      save the logical offset, so if we happen to try and map that extent we can be
      sure to set FIEMAP_EXTENT_LAST.
      
      With this patch we now pass xfstest 225, which we never have before.

      Btrfs - fix race between btrfs_get_sb() and umount · 619c8c76
      Ian Kent authored
      
      
      When mounting a btrfs file system btrfs_test_super() may attempt to
      use sb->s_fs_info, the btrfs root, of a super block that is going away
      and that has had the btrfs root set to NULL in its ->put_super(). But
      if the super block is going away it cannot be an existing super block
      so we can return false in this case.
