MFV r258371,r258372: 4101 metaslab_debug should allow for fine-grained control
4101 metaslab_debug should allow for fine-grained control 4102 space_maps should store more information about themselves 4103 space map object blocksize should be increased 4104 ::spa_space no longer works 4105 removing a mirrored log device results in a leaked object 4106 asynchronously load metaslab illumos/illumos-gate@0713e232b7712cd27d99e1e935ebb8d5de61c57d Note that some tunables have been removed and some new tunables have been added. Of particular note, FreeBSD-only knob vfs.zfs.space_map_last_hope is removed as it was a nop for some time now (after one of the previous merges from upstream). MFC after: 11 days Sponsored by: HybridCluster [merge]
