Martin Matuska e70664bafc MFV v242732: ... Merge the ZFS I/O deadman thread from vendor (illumos). This feature panics the system on hanging ZFS I/O, helps debugging and resumes failed service. The panic behavior can be controlled with the loader-only tunables: vfs.zfs.deadman_enabled (enable or disable panic on stalled ZFS I/O) vfs.zfs.deadman_synctime (expiration time for stalled ZFS I/O) By default, ZFS I/O deadman is enabled by default on amd64 and i386 excluding virtual guest machines.
