Linus Torvalds e93dd910b9 A set of device-mapper fixes for 3.12. 
A few fixes for dm-snapshot, a 32 bit fix for dm-stats, a couple error
 handling fixes for dm-multipath.  A fix for the thin provisioning target
 to not expose non-zero discard limits if discards are disabled.
 
 Lastly, add two DM module parameters which allow users to tune the
 emergency memory reserves that DM mainatins per device -- this helps fix
 a long-standing issue for dm-multipath.  The conservative default
 reserve for request-based dm-multipath devices (256) has proven
 problematic for users with many multipathed SCSI devices but relatively
 little memory.  To responsibly select a smaller value users should use
 the new nr_bios tracepoint info (via commit 75afb352 "block: Add nr_bios
 to block_rq_remap tracepoint") to determine the peak number of bios
 their workloads create.
