      Btrfs: use right range to find checksum for compressed extents · 192000dd
      Liu Bo authored
      For compressed extents, the range of checksum is covered by disk length,
      and the disk length is different with ram length, so we need to use disk
      length instead to get us the right checksum.

      Btrfs: fix panic when recovering tree log · b0175117
      Josef Bacik authored
      A user reported a BUG_ON(ret) that occured during tree log replay.  Ret was
      -EAGAIN, so what I think happened is that we removed an extent that covered
      a bitmap entry and an extent entry.  We remove the part from the bitmap and
      return -EAGAIN and then search for the next piece we want to remove, which
      happens to be an entire extent entry, so we just free the sucker and return.
      The problem is ret is still set to -EAGAIN so we trip the BUG_ON().  The
      user used btrfs-zero-log so I'm not 100% sure this is what happened so I've
      added a WARN_ON() to catch the other possibility.  Thanks,

      Btrfs: do not allow logged extents to be merged or removed · 201a9038
      Josef Bacik authored
      We drop the extent map tree lock while we're logging extents, so somebody
      could come in and merge another extent into this one and screw up our
      logging, or they could even remove us from the list which would keep us from
      logging the extent or freeing our ref on it, so we need to make sure to not
      clear LOGGING until after the extent is logged, and then we can merge it to
      adjacent extents.  Thanks,
