2.6.18 seems to get caught in an infinite loop when cancel_rearming_delayed_workqueue is called more than once, so this switches to cancel_delayed_work, which is arguably more correct. Also, balance_dirty_pages can run into problems with 2.6.18 based kernels because it doesn't have the per-bdi dirty limits. This avoids calling balance_dirty_pages on the btree inode unless there is actually something to balance, which is a good optimization in general. Finally there's a compile fix for ordered-data.h Signed-off-by: -

balance level starts by trying to empty the middle block, and then pushes from the right to the middle. This might empty the right block and leave a small number of pointers in the middle. Signed-off-by: -

The generic O_DIRECT code assumes all the bios have the same bdev, which isn't true for multi-device btrfs. Signed-off-by: -

This allows other code that needs to walk every device in the FS to do so without locking against allocations. Signed-off-by: -

btrfs_invalidatepage is not allowed to leave pages around on the lru. Any such pages will trigger an oops later on because the VM will see page->private and assume it is a buffer head. This also forces extra flushes of the async work queues before dropping all the pages on the btree inode during unmount. Left over items on the work queues are one possible cause of busy state ranges during truncate_inode_pages. Signed-off-by: -

The btree inode should only have a single extent_map in the cache, it doesn't make sense to ever drop it. Signed-off-by: -

It was testing the bio before doing logical->physical mapping, so the test was always wrong. Signed-off-by: -

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. Signed-off-by: -

This isn't required anymore because we don't reallocate blocks that have already been written in this transaction. Signed-off-by:
