  13     btrfs: pass fs_info to trace_btrfs_transaction_commit
  14
  15     The root on the trans->root can be anything, and generally we're
  16     committing from the transaction kthread so it's usually the tree_root.
  17     Change this to just take an fs_info, and to maintain compatibility
  18     simply put the ROOT_TREE_OBJECTID as the root objectid for the
  19     tracepoint.  This will allow use to remove trans->root.
