The data read retry code needs to find the logical disk block before it can resubmit new bios. But, finding this block isn't allowed to take the fs_mutex because that will deadlock with a number of different callers. This changes the retry code to use the extent map cache instead, but that requires the extent map cache to have the extent we're looking for. This is a problem because btrfs_drop_extent_cache just drops the entire extent instead of the little tiny part it is invalidating. The bulk of the code in this patch changes btrfs_drop_extent_cache to invalidate only a portion of the extent cache, and changes btrfs_get_extent to deal with the results.

Block headers now store the chunk tree uuid Chunk items records the device uuid for each stripes Device extent items record better back refs to the chunk tree Block groups record better back refs to the chunk tree The chunk tree format has also changed. The objectid of BTRFS_CHUNK_ITEM_KEY used to be the logical offset of the chunk. Now it is a chunk tree id, with the logical offset being stored in the offset field of the key. This allows a single chunk tree to record multiple logical address spaces, upping the number of bytes indexed by a chunk tree from 2^64 to 2^128. Signed-off-by: NChris Mason <chris.mason@oracle.com>
