Chris Mason 940100a4a7 Btrfs: be more selective in the defrag ioctl ... The btrfs defrag ioctl had some bugs around delalloc accounting, and it wasn't properly skipping pages that were not in the mapping. It wasn't properly clearing the page checked flag, which could make the writeback code ignore the page forever while pinning it as dirty. This commit fixes those problems and makes defrag a little smarter. It skips holes and it doesn't waste time defragging large extents. If a tiny extent comes before a very large extent, it will defrag both of them to make sure the tiny extent ends up next to something big.
