It was originally written by Sun as part of the STF (Solaris test framework). They open sourced it in OpenSolaris, then HighCloud partially ported it to FreeBSD, and Spectra Logic finished the port. We also added many testcases, fixed many broken ones, and converted them all to the ATF framework. We've had help along the way from avg, araujo, smh, and brd. By default most of the tests are disabled. Set the disks Kyua variable to enable them. Submitted by: asomers, will, justing, ken, brd, avg, araujo, smh Sponsored by: Spectra Logic Corp, HighCloud
