Add the ability to collect I/O statistics on user-defined regions of a
...
device-mapper device. This dm-stats code required the reintroduction of
a div64_u64_rem() helper, but as a separate method that doesn't slow
down div64_u64() -- especially on 32-bit systems.
Allow the error target to replace request-based DM devices
(e.g. multipath) in addition to bio-based DM devices.
Various other small code fixes and improvements to thin-provisioning, DM
cache and the DM ioctl interface.
