Liu Bo 6288d6eabc Btrfs: use the correct type when creating cow dio extent 
'BTRFS_ORDERED_REGULAR' was introduced for the cow case in patch
'Btrfs: specify a new ordered extent type for create_io_em',
but it missed the directIO cow case.

Filipe Manana b1517622f2 Btrfs: fix deadlock between dedup on same file and starting writeback 
If we are deduping two ranges of the same file we need to make sure that
we lock all pages in ascending order, that is, lock first the pages from
the range with lower offset and then the pages from the other range, as
otherwise we can deadlock with a concurrent task that is starting delalloc
(writeback). Example trace:

                                                        locked previously

So fix this by making sure that during a dedup we always lock first the
pages from the range with lower offset.

Jeff Mahoney 71367b3fa7 btrfs: use btrfs_debug instead of pr_debug in transaction abort 
Commit e5d6b12fe1 (Btrfs: don't WARN() in btrfs_transaction_abort() for
IO errors) added a pr_debug call to be printed when a transaction is
aborted with -EIO instead of WARN.  btrfs_debug prints which file system
the message is associated with so let's use that instead.

Jeff Mahoney 77ab86bf1c btrfs: free-space-cache, clean up unnecessary root arguments 
The free space cache APIs accept a root but always use the tree root.

Also, btrfs_truncate_free_space_cache accepts a root AND an inode but
the inode always points to the root anyway, so let's just pass the inode.

Jeff Mahoney 87bde3cdfc btrfs: pass fs_info to (more) routines that are only called with extent_root 
Outside of interactions with qgroups, the roots passed in extent-tree.c
are usually passed to ensure that we don't do refcounts on log trees or
to get the allocation profile for an allocation request.  Otherwise, it
operates on the extent root.  This patch converts some more routines in
extent-tree.c that are always called with the extent root to accept
an fs_info instead.

Qu Wenruo fb235dc06f btrfs: qgroup: Move half of the qgroup accounting time out of commit trans 
Just as Filipe pointed out, the most time consuming parts of qgroup are
btrfs_qgroup_account_extents() and
btrfs_qgroup_prepare_account_extents().
Which both call btrfs_find_all_roots() to get old_roots and new_roots
ulist.

What makes things worse is, we're calling that expensive
btrfs_find_all_roots() at transaction committing time with
TRANS_STATE_COMMIT_DOING, which will blocks all incoming transaction.

Such behavior is necessary for @new_roots search as current
btrfs_find_all_roots() can't do it correctly so we do call it just
before switch commit roots.

However for @old_roots search, it's not necessary as such search is
based on commit_root, so it will always be correct and we can move it
out of transaction committing.

This patch moves the @old_roots search part out of
commit_transaction(), so in theory we can half the time qgroup time
consumption at commit_transaction().

But please note that, this won't speedup qgroup overall, the total time
consumption is still the same, just reduce the performance stall.
