  Fix btrfs_get_extent and get_block corner cases, and disable O_DIRECT reads · e1c4b745
  由 Chris Mason 提交于 4月 22, 2008
```
The generic O_DIRECT code assumes all the bios have the same bdev,
which isn't true for multi-device btrfs.

  Btrfs: Use the extent map cache to find the logical disk block during data retries · 3b951516
  由 Chris Mason 提交于 4月 17, 2008
```
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.

  Btrfs: Add chunk uuids and update multi-device back references · e17cade2
  由 Chris Mason 提交于 4月 15, 2008
```
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.
