[BUG]
For btrfs:qgroup_meta_reserve event, the trace event can output garbage:
qgroup_meta_reserve: 9c7f6acc-b342-4037-bc47-7f6e4d2232d7: refroot=5(FS_TREE) type=DATA diff=2
qgroup_meta_reserve: 9c7f6acc-b342-4037-bc47-7f6e4d2232d7: refroot=5(FS_TREE) type=0x258792 diff=2
The @type can be completely garbage, as DATA type is not possible for
trace_qgroup_meta_reserve() trace event.
[CAUSE]
Ther are several problems related to qgroup trace events:
- Unassigned entry member
Member entry::type of trace_qgroup_update_reserve() and
trace_qgourp_meta_reserve() is not assigned
- Redundant entry member
Member entry::type is completely useless in
trace_qgroup_meta_convert()
