5e5745dcaf Btrfs: Add full_scan parameter to find_search_start 
This patch adds a new parameter 'full_scan' to 'find_search_start',
thereby 'find_search_start' can know whether 'find_free_extent' is in
full scan phrase. I feel that 'find_search_start' should skip calling
'btrfs_find_block_group' when 'find_free_extent' is in full scan
phrase. In my test on a 2GB volume, Oops occurs when space usage is
about 76%. After apply the patch,  Oops occurs when space usage is
near 100%.

324ae4df00 Btrfs: Add block group pinned accounting back 
This patch adds a helper function 'update_pinned_extents' to
extent-tree.c. The usage of the helper function is similar to
'update_block_group',  the last parameter of the function indicates
pin vs unpin.

6702ed490c Btrfs: Add run time btree defrag, and an ioctl to force btree defrag 
This adds two types of btree defrag, a run time form that tries to
defrag recently allocated blocks in the btree when they are still in ram,
and an ioctl that forces defrag of all btree blocks.

File data blocks are not defragged yet, but this can make a huge difference
in sequential btree reads.

Before, snapshot deletion was a single atomic unit.  This caused considerable

snapshot deletion is, and to resume where it left off.
