That's not really a shortcut, per se.  RAID10 in Linux is not
necessarily similar to RAID1+0.  The default, "near" layout is the
classic 1+0 layout, but other modes of operation are supported by the
RAID10 driver.

Correct.  There's no such driver.

If you built a RAID0 array of RAID6 arrays, then you'd fail a disk by
marking it failed and removing it from whichever RAID6 array it was a
member of, in the same fashion as you'd remove it from any other array type.
