    ZFS FreeBSD 11 ZFS issues, are they a problem in R12?

    Hi, I was reading the errata for 11 and 12. It looks like there are some serious issues with ZFS in R11 but the R12 errata does not include any ZFS issues. Is it the case that those issues including the "no work around" for R11 do not exist in R12, because they were fixed in code, or have...
