yes.

they work for me. I don't use latest-and-greatest kernels and I use vanilla 
kernel.org sources. 

zpool status
  pool: zfstank

status: One or more devices has experienced an error resulting in data
        corruption.  Applications may be affected.

        entire pool from backup.

errors: 9 data errors, use '-v' for a list

those errors were caused by a memory glitch (and are video files... so... I 
don't even care about them - also they are still on two different backup 
media...), But zfs caught these errors. ext4? I really doubt it.
