Chris Mason 93a6925ec1 Btrfs: Fix extra link count dec in rename

Chris Mason 5ce14bbcdd Btrfs: Find and remove dead roots the first time a root is loaded. 
Dead roots are trees left over after a crash, and they were either in the
process of being removed or were waiting to be removed when the box crashed.
Before, a search of the entire tree of root pointers was done on mount
looking for dead roots.  Now, the search is done the first time we load
a root.

This makes mount faster when there are a large number of snapshots, and it
enables the block accounting code to properly update the block counts on
the latest root as old versions of the root are reaped after a crash.

Christoph Hellwig 0e2752a72c Btrfs: [PATCH] extent_map: add writepage_end_io hook 
XFS updates the ondisk inode size only after the data I/O has finished,
so it needs a hook when the writepage end_bio handler has finished.

Might not be worth applying as-is as the per-page callback is very
ineffcient.  What XFS really wants is a callback when writeout of a
whole extent has completed.  This delayed i_size updates scheme might
be worthwile for btrfs aswell, btw.

Christoph Hellwig b06355f0fe Btrfs: [PATCH] extent_map: make the writepage_io hook optional 
The writepage_io is not mandatory, e.g. my port of xfs to the extent_map
code does not have one for now.  So handle a NULL pointer gracefully
here.

Christoph Hellwig d396c6f554 Btrfs: [PATCH] extent_map: provide generic bmap 
generic_bmap is completely trivial, while the extent to bh mapping in
btrfs is rather complex.  So provide a extent_bmap instead that takes
a get_extent callback and can be used by filesystem using the extent_map
code.

Christoph Hellwig 90f1c19a9f Btrfs: [PATCH] extent_map: fix locking for bio completion 
The bio completion handlers can be run in any context, e.g. when using
the old ide driver they run in hardirq context with irqs disabled so
lockdep rightfully warns about using write_lock_irq useage in these
handlers.

This patch switches clear_extent_bit and set_extent_bit to
write_lock_irqsave to fix this problem.

Yan Zheng noticed that set_extent_bit was exiting too early when there
was a hole in the map.  The fix is to reorder the tests to check for the

Chris Mason 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.

Chris Mason 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.
