Is it expected because it's a bug, or is it a bug that is not going to be fixed
and so I should expect it? Is there a bug/defect I can keep an eye on in one
of the Opensolaris bug/defect interfaces that will help me figure out what's
going on with it and when a solution is expected?
See:
6922161 zio_ddt_free is single threaded with performance impact
6924824 destroying a dedup-enabled dataset bricks system
Both issues stem from the fact that free operations used to be in-memory
only but with dedup enabled can result in synchronous I/O to disks in
syncing context.
