Previous patches make the allocater return -ENOSPC if there is
no unreserved free meta space. This patch updates tree log code
and various other places to propagate/handle the ENOSPC error.

Introduce metadata reservation context for delayed allocation and
update various related functions.
This patch also introduces EXTENT_FIRST_DELALLOC control bit for
set/clear_extent_bit. It tells set/clear_bit_hook whether they
are processing the first extent_state with EXTENT_DELALLOC bit
set.
Shrink delay allocated space in a synchronized manner is more
controllable than flushing all delay allocated space in an async
thread.

The size of reserved space is stored in space_info. If block groups
of different raid types are linked to separate space_info, changing
allocation profile will corrupt reserved space accounting.

Introducing contexts for metadata reseravtion has two major
advantages. First, it makes metadata reseravtion more traceable.
Second, it can reclaim freed space and re-add them to the itself
after transaction committed.

Hi all,
It seems like memory barrier is not required in cached_block_group.I
am looking at kernel 2.6.34-rc2.
cache_block_group(struct btrfs_block_group_cache *cache)
{
smp_mb();
if (cache-cached != BTRFS_CACHE_NO)
return 0;
}
This function is called from btrfs_alloc_logged_file_extent
