Thanks, Alasdair ---------------------------------------------------------------- The main addition here is a long-desired target framework to allow an SSD to be used as a cache in front of a slower device. Cache tuning is delegated to interchangeable policy modules so these can be developed independently of the mechanics needed to shuffle the data around. Other than that, kcopyd users acquire a throttling parameter, ioctl buffer usage gets streamlined, more mempool reliance is reduced and there are a few other bug fixes and tidy-ups. ---------------------------------------------------------------- Alasdair G Kergon (6): dm: remove CONFIG_EXPERIMENTAL dm: clean up clone_bio dm: rename request variables to bios dm: rename bio cloning functions dm: refactor bio cloning dm: add target num_write_bios fn Heinz Mauelshagen (1): dm cache: add cleaner policy Joe Thornber (7): dm persistent data: add btree_walk dm bio prison: pass cell memory in dm thin: remove cells from stack dm persistent data: add transactional array dm persistent data: add bitset dm: add cache target dm cache: add mq policy Jun'ichi Nomura (3): dm: do not replace bioset for request based dm dm: remove unused _rq_bio_info_cache dm: merge io_pool and tio_pool Kees Cook (1): dm persistent data: remove CONFIG_EXPERIMENTAL Mike Christie (1): dm: fix limits initialization when there are no data devices Mike Snitzer (3): dm thin: support a non power of 2 discard_granularity dm thin: use block_size_is_power_of_two dm persistent data: set some btree fn parms const Mikulas Patocka (7): dm: fix truncated status strings dm bufio: use WRITE_FLUSH instead of REQ_FLUSH dm snapshot: add missing module aliases dm ioctl: introduce ioctl_flags dm ioctl: optimize functions without variable params dm ioctl: allow message to return data dm kcopyd: introduce configurable throttling Wang Sheng-Hui (1): dm table: remove superfluous variable reset Documentation/device-mapper/cache-policies.txt | 77 + Documentation/device-mapper/cache.txt | 243 +++ drivers/md/Kconfig | 55 +- drivers/md/Makefile | 6 + drivers/md/dm-bio-prison.c | 155 +- drivers/md/dm-bio-prison.h | 58 +- drivers/md/dm-bufio.c | 2 +- drivers/md/dm-cache-block-types.h | 54 + drivers/md/dm-cache-metadata.c | 1146 +++++++++++ drivers/md/dm-cache-metadata.h | 142 ++ drivers/md/dm-cache-policy-cleaner.c | 464 +++++ drivers/md/dm-cache-policy-internal.h | 124 ++ drivers/md/dm-cache-policy-mq.c | 1195 +++++++++++ drivers/md/dm-cache-policy.c | 161 ++ drivers/md/dm-cache-policy.h | 228 +++ drivers/md/dm-cache-target.c | 2584 ++++++++++++++++++++++++ drivers/md/dm-crypt.c | 45 +- drivers/md/dm-delay.c | 12 +- drivers/md/dm-flakey.c | 11 +- drivers/md/dm-ioctl.c | 166 +- drivers/md/dm-kcopyd.c | 121 +- drivers/md/dm-linear.c | 13 +- drivers/md/dm-mpath.c | 12 +- drivers/md/dm-raid.c | 10 +- drivers/md/dm-raid1.c | 17 +- drivers/md/dm-snap.c | 33 +- drivers/md/dm-stripe.c | 27 +- drivers/md/dm-table.c | 11 +- drivers/md/dm-target.c | 2 +- drivers/md/dm-thin-metadata.c | 12 +- drivers/md/dm-thin.c | 277 ++- drivers/md/dm-verity.c | 8 +- drivers/md/dm-zero.c | 2 +- drivers/md/dm.c | 452 +++-- drivers/md/persistent-data/Kconfig | 2 +- drivers/md/persistent-data/Makefile | 2 + drivers/md/persistent-data/dm-array.c | 808 ++++++++ drivers/md/persistent-data/dm-array.h | 166 ++ drivers/md/persistent-data/dm-bitset.c | 163 ++ drivers/md/persistent-data/dm-bitset.h | 165 ++ drivers/md/persistent-data/dm-block-manager.c | 1 + drivers/md/persistent-data/dm-btree-internal.h | 1 + drivers/md/persistent-data/dm-btree-spine.c | 7 + drivers/md/persistent-data/dm-btree.c | 52 + drivers/md/persistent-data/dm-btree.h | 15 +- include/linux/device-mapper.h | 49 +- include/linux/dm-kcopyd.h | 25 +- include/uapi/linux/dm-ioctl.h | 11 +- 48 files changed, 8791 insertions(+), 601 deletions(-) create mode 100644 Documentation/device-mapper/cache-policies.txt create mode 100644 Documentation/device-mapper/cache.txt create mode 100644 drivers/md/dm-cache-block-types.h create mode 100644 drivers/md/dm-cache-metadata.c create mode 100644 drivers/md/dm-cache-metadata.h create mode 100644 drivers/md/dm-cache-policy-cleaner.c create mode 100644 drivers/md/dm-cache-policy-internal.h create mode 100644 drivers/md/dm-cache-policy-mq.c create mode 100644 drivers/md/dm-cache-policy.c create mode 100644 drivers/md/dm-cache-policy.h create mode 100644 drivers/md/dm-cache-target.c create mode 100644 drivers/md/persistent-data/dm-array.c create mode 100644 drivers/md/persistent-data/dm-array.h create mode 100644 drivers/md/persistent-data/dm-bitset.c create mode 100644 drivers/md/persistent-data/dm-bitset.h -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
