    Btrfs: ensure an entire eb is written at once · 0b32f4bb

    This patch simplifies how we track our extent buffers.  Previously we could exit
    writepages with only having written half of an extent buffer, which meant we had
    to track the state of the pages and the state of the extent buffers differently.
    Now we only read in entire extent buffers and write out entire extent buffers,
    this allows us to simply set bits in our bflags to indicate the state of the eb
    and we no longer have to do things like track uptodate with our iotree.  Thanks,
