Currently, after rebuild (aka sequential resilver), checksum errors can be seen sometimes on the spare vdev or draid spare. On my laptop, it happens from 2 to 4 times of running redundancy_draid_spare1 test in a loop for 100 times. It looks like there's a race in vdev_rebuild_thread() when the rebuild of space map ranges is finished and we re-enable allocations from the metaslab too soon: a new allocations may happen from that metaslab before txg with the rebuilt ranges is sync-ed, causing undesirable interference. Solution: wait for the txg to be sync-ed before enabling metaslab.
