Filipe Manana a8d1f0b539 btrfs: reduce size of struct btrfs_block_group 
We currently have several holes in the structure:

  struct btrfs_block_group {
        struct btrfs_fs_info *     fs_info;              /*     0     8 */
        struct btrfs_inode *       inode;                /*     8     8 */
        spinlock_t                 lock __attribute__((__aligned__(4))); /*    16     4 */

        /* XXX 4 bytes hole, try to pack */

        u64                        start;                /*    24     8 */

  } __attribute__((__aligned__(8)));

Reorder some fields to eliminate the holes while keeping closely related
or frequently accessed fields together. After the reordering the size of
the structure is reduced down to 632 bytes and the number of cache lines
decreases from 11 to 10. We can still only pack 6 block groups per 4K page
but on a 64K page system we will now be able to pack 103 block groups
instead of 97. The new structure layout, on a release kernel, is the
following:

  struct btrfs_block_group {
        struct btrfs_fs_info *     fs_info;              /*     0     8 */
        struct btrfs_inode *       inode;                /*     8     8 */

        unsigned int               ro;                   /*    20     4 */
