dm space maps: improve performance with inc/dec on ranges of blocks

2021-06-04T16:07:22Z

When we break sharing on btree nodes we typically need to increment the reference counts to every value held in the node. This can cause a lot of repeated calls to the space maps. Fix this by changing the interface to the space map inc/dec methods to take ranges of adjacent blocks to be operated on. For installations that are using a lot of snapshots this will reduce cpu overhead of fundamental operations such as provisioning a new block, or deleting a snapshot, by as much as 10 times.

dm persistent data: fix return type of shadow_root()

2021-02-03T15:10:05Z

shadow_root() truncates 64-bit dm_block_t into 32-bit int. This is not an issue in practice, since dm metadata as of v5.11 can only hold at most 4161600 blocks (255 index entries * ~16k metadata blocks). Nevertheless, this can confuse users debugging some specific data corruption scenarios. Also, DM_SM_METADATA_MAX_BLOCKS may be bumped in the future, or persistent-data may find its use in other places. Therefore, switch the return type of shadow_root from int to dm_block_t.
