bio-based configurations that don't haave a SCSI device handler. - Fix dm-btree removal to ensure non-root btree nodes have at least (max_entries / 3) entries. This resolves userspace thin_check utility's report of "too few entries in btree_node". - Fix both the DM thin-provisioning and dm-clone targets to properly flush the data device prior to metadata commit. This resolves the potential for inconsistency across a power loss event when the data device has a volatile writeback cache. - Small documentation fixes to dm-clone and dm-integrity. -----BEGIN PGP SIGNATURE----- iQFHBAABCAAxFiEEJfWUX4UqZ4x1O2wixSPxCi2dA1oFAl3yU6sTHHNuaXR6ZXJA cmVkaGF0LmNvbQAKCRDFI/EKLZ0DWvO9B/0dsIxL09sWSHPe+wuzy7WXAOCHVm04 27dloxNzgXGFT5ftvU+JpLParOtDfJ2ral2BVGExjGzMs4QP8ZLrn5UuTFuR7nXi FDaypaCelRsh1/204bKDgb22vaZIAZFu7Rz2YsAzWqpCJZDjN5cgy9xz4GmCvXRt R13Qq8Dia4scR/y+xCkm5s4wH2xGz1CDmpSPzbLTpTfkMfY5yzp6Gzaipj4Fwq78 dDERNZNuabVr2o8mt8OGd/s1h4QtiJps1J8NV2He5C3Bf8daaFVkHDCl75+P2KQC ++VaIS/l1TfcOyDJmoztg7w2gmLkTxEskVpN/UQD/Ut9D5m7P9S7uaQg =6t9f -----END PGP SIGNATURE----- Merge tag 'for-5.5/dm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper fixes from Mike Snitzer: - Fix DM multipath by restoring full path selector functionality for bio-based configurations that don't haave a SCSI device handler. - Fix dm-btree removal to ensure non-root btree nodes have at least (max_entries / 3) entries.
