btrfs: pretty print leaked root name I'm a actual human being so am incapable of converting u64 to s64 in my head, so add a helper to get the pretty name of a root objectid and use that helper to spit out the name for any special roots for leaked roots, so I don't have to scratch my head and figure out which root I messed up the refs for.

btrfs: print-tree: debugging output enhancement This patch enhances the following things: - tree block header * add generation and owner output for node and leaf - node pointer generation output - allow btrfs_print_tree() to not follow nodes * just like btrfs-progs Please note that, although function btrfs_print_tree() is not called by anyone right now, it's still a pretty useful function to debug kernel. So that function is still kept for later use. Signed-off-by: Qu Wenruo <wqu@suse.com> Reviewed-by: Lu Fengqi <lufq.fnst@cn.fujitsu.com> Signed-off-by: David Sterba <dsterba@suse.com>

btrfs: print the actual offset in btrfs_root_name We're supposed to print the root_key.offset in btrfs_root_name in the case of a reloc root, not the objectid. Fix this helper to take the key so we have access to the offset when we need it.
