The commits in question are the following: [1] r236884: zfs feature support, June 11, MFC after 1 month [2] r238422: fixes for defer-destroy, July 13, MFC after 1 week [3] r238926: fixes for zpool feature support, July 30, MFC after 2 weeks There may be others, but those appear to be the main ones for enabling async snapshot destroy. The mailing list thread (ZFS new SPA) includes a link [4] which includes a file called 9-stable-zfs-features.patch.gz which appears to be what I want to test. Wondering if anyone has tested it as yet.
