Mike, Mikulas, dm-crypt splitting a regular write used for emulating a zone append operation breaks the writeen sector return for zone append, causing all sorts of issues (e.g. corruptions) with file systems using the zone append operation (btrfs, xfs). The first patch addresses this issue. The second patch adds a check to detect if a DM target attempts to split such BIO.
