Linus Torvalds b49249d103 Miscellaneous device-mapper fixes, cleanups and performance improvements.
Of particular note:
 - Disable broken WRITE SAME support in all targets except linear and striped.
   Use it when kcopyd is zeroing blocks.
 - Remove several mempools from targets by moving the data into the bio's new
   front_pad area(which dm calls 'per_bio_data').
 - Fix a race in thin provisioning if discards are misused.
 - Prevent userspace from interfering with the ioctl parameters and
   use kmalloc for the data buffer if it's small instead of vmalloc.
 - Throttle some annoying error messages when I/O fails.
