'GPL-2.0-only' is used instead of 'GPL-2.0' because SPDX has
deprecated its use.

dm space maps: improve performance with inc/dec on ranges of blocks2021-06-04T16:07:22+00:00Joe Thornberejt@redhat.com2021-04-13T10:03:45+00:00urn:sha1:be500ed721a6ec8d49bf0814c277ce7162acee0e
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.
