Linus Torvalds 7426d62871 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.
