18f16f7ba6 Btrfs: Fix for insert_inline_extent to handle offset != 0 
This modifies inline extent size calculation, so that
insert_inline_extent can handle the case that parameter 'offset' is
not zero; it also a few codes to zero uninitialized area in inline
extent.

d3c2fdcf7b Btrfs: Use balance_dirty_pages_nr on btree blocks 
btrfs_btree_balance_dirty is changed to pass the number of pages dirtied
for more accurate dirty throttling.  This lets the VM make better decisions
about when to force some writeback.

011410bd85 Btrfs: Add more synchronization before creating a snapshot 
File data checksums are only done during writepage, so we have to make sure
all pages are written when the snapshot is taken.  This also adds some
locking so that new writes don't race in and add new dirty pages.

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.

ec6b910fb3 Btrfs: trivial include fixups 
Almost none of the files including module.h need to do so,
remove them.

Include sched.h in extent-tree.c to silence a warning about cond_resched()
being undeclared.
