One of my old patches introduces a new bug to
btrfs_drop_extents(changeset 275). Inline extents are not truncated
properly when "extent_end == end", it can trigger the BUG_ON at
file.c:600.  I hope I don't introduce new bug this time.

Hello everybody,

compiling btrfs into the kernel results in section mismatch warnings. __exit
functions are called where they are not allowed to. The attached patch fixes
this for me. Not sure if it is correct though.

Josef Bacik 1caf9342fc Btrfs: Make ACLs return EOPNOTSUPP for now 
There was a slight problem with ACL's returning EINVAL when you tried to set an
ACL.  This isn't correct, we should be returning EOPNOTSUPP, so I did a very
ugly thing and just commented everybody out and made them return EOPNOTSUPP.
This is only temporary, I'm going back to implement ACL's, but Chris wants to
push out a release so this will suffice for now.

Also Yan suggested setting reada to -1 in the delete case to enable backwards
readahead, and in the listxattr case I moved path->reada = 2; to after the if
(!path) check so we can avoid a possible null dereference.  Thank you,

This patch adds a new parameter 'full_scan' to 'find_search_start',

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

Yan 008630c17c Properly delete csum item in btrfs_truncate_in_trans. 
When 'item_end' is equal to 'inode->i_size',   'found_type' is updated
and current item is skipped. This behavior is correct for extent item,
but incorrect for csum item. For example, there is a csum item with
'offset == 0'. When deleting the inode,  'inode->i_size' is set to 0,
so the csum item isn't deleted.

1) Most btrfs_drop_extent callers will try to leave the inline extents in

required.

2) writepage can now update the inline extent, allowing mmap writes to
go directly into the inline extent.

3) btrfs_truncate_in_transaction truncates inline extents

4) extent_map.c fixed to not merge inline extent mappings and hole
mappings together

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.

Chris Mason 4b52dff6d3 Btrfs: Fix super block updates during transaction commit
