dm table: propagate QUEUE_FLAG_NO_SG_MERGE (2014-08-10 20:54:49 -0400)
Please pull, thanks.
Mike
----------------------------------------------------------------
. Allow the thin target to paired with any size external origin; also
allow thin snapshots to be larger than the external origin.
. Add support for quickly loading a repetitive pattern into the
dm-switch target.
. Use per-bio data in the dm-crypt target instead of always using a
mempool for each allocation. Required switching to kmalloc alignment
for the bio slab.
. Fix DM core to properly stack the QUEUE_FLAG_NO_SG_MERGE flag
. Fix the dm-cache and dm-thin targets' export of the minimum_io_size to
match the data block size -- this fixes an issue where mkfs.xfs would
improperly infer raid striping was in place on the underlying storage.
. Small cleanups in dm-io, dm-mpath and dm-cache
----------------------------------------------------------------
Jeff Moyer (1):
dm table: propagate QUEUE_FLAG_NO_SG_MERGE
Joe Thornber (5):
dm io: simplify dec_count and sync_io
dm thin: switch to an atomic_t for tracking pending new block preparations
dm thin: relax external origin size constraints
dm cache: simplify deferred set reference count increments
dm cache: fail migrations in the do_worker error path
Mike Snitzer (4):
dm mpath: eliminate pg_ready() wrapper
dm cache metadata: use dm-space-map-metadata.h defined size limits
dm thin: set minimum_io_size to pool's data block size
dm cache: set minimum_io_size to cache's data block size
Mikulas Patocka (5):
dm table: make dm_table_supports_discards static
block: use kmalloc alignment for bio slab
dm crypt: use per-bio data
dm switch: factor out switch_region_table_read
dm switch: efficiently support repetitive patterns
