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. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (GNU/Linux) iQEcBAABAgAGBQJSQMVHAAoJEMUj8QotnQNaOXgIAJS6/XJKMoHfiDJ9M+XD34rZ Uyr9TEnubX3DKCRBiY23MUcCQn3fx6BjCGv5/c8L4jQFIuLyDi2yatqpwXcbGSJh G/S/y6u0Axek+ew7TS80OFop4nblW6MoKnoh9/4N55Ofa+1WvKM4ERUGjHGbauyS TxmLQPToCFPLYRIOZ+imd6hQuIZ1+FFdJFvi7kY9O6Llx2sLD6fWi1iruBd/Da2H ByMX3biGN45mSpcBzRbSC/FkJ9CRIvT9n82BDPS0o3Tllt8NaVlEDaovB7h4ncc0 bFuT2Z3Q38B9uZ8Lj0bqdGzv3kXMLCkLo6WhWjyUt84hmDPAzRpBwt60jUqWyZs= =bjVp -----END PGP SIGNATURE----- Merge tag 'dm-3.12-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device-mapper fixes from Mike Snitzer: "A few fixes for dm-snapshot, a 32 bit fix for dm-stats, a couple error handling fixes for dm-multipath.
