While running this I observed other ZFS volumes randomly unmounting, and mount points owner being spuriously zeroed (set to root). == Fix == https://github.com/openzfs/zfs/commit/d1b84da8c1a69c084f04b504beefe804591bca07 == Test == Steps are laid out in the ZFS issue: https://github.com/openzfs/zfs/issues/9560 == Regression Potential == Limited to the behavior of zfs mount when a previous attempt to mount has failed, or is still in progress. Changes the behavior in that case to failure, instead of double-free. Example case of running into this bug, with dmesg: https://pastebin.com/YRXW8WgM $ lsb_release -a No LSB modules are available.
