btrfs: qgroup: Update trace events for metadata reservation
Now trace_qgroup_meta_reserve() will have extra type parameter. And introduce two new trace events: 1) trace_qgroup_meta_free_all_pertrans() For btrfs_qgroup_free_meta_all_pertrans() 2) trace_qgroup_meta_convert() For btrfs_qgroup_convert_reserved_meta() Signed-off-by: Qu Wenruo <wqu@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>
