So I tried to build this..you won't believe what happened next:

  CC [M]  fs/btrfs/transaction.o
fs/btrfs/transaction.c:570:28: error: conflicting types for 'btrfs_start_transaction'
 struct btrfs_trans_handle *btrfs_start_transaction(struct btrfs_root *root,
                            ^
In file included from fs/btrfs/transaction.c:28:0:
fs/btrfs/transaction.h:186:28: note: previous declaration of 'btrfs_start_transaction' was here
 struct btrfs_trans_handle *btrfs_start_transaction(struct btrfs_root *root,
                            ^
scripts/Makefile.build:258: recipe for target 'fs/btrfs/transaction.o' failed

You need to update transaction.h as well.

-h
