Hi,

This is version 7 of the patch series to introduce block-level provisioning primitives [1]. The current series is rebased on: (2d1bcbc6cd70 Merge tag 'probes-fixes-v6.4-rc1'...).

Changelog:

v7:
- Fold up lo_req_provision() into lo_req_fallocate().
- Propagate error on failure to provision from the blkdev_issue_provision().
- Set 'max_provision_granularity' in thin_ctr.
- Fix positioning of 'max_provision_sectors' in pool_ctr.
- Add provision bios into process_prepared_mapping() to prevent the bio from being reissued to the underlying thinpool.
