Mike Gerdts 94c43313ab blob: snapshots of esnap clones ... An esnap clone needs special handling as snapshots are created and removed. In particular: the following must exist on the blob that directly references the external snapshot and must be removed from others: - Ensure SPDK_BLOB_EXTERNAL_SNAPSHOT invalid flag exists only on the esnap clone. - Ensure BLOB_EXTERNAL_SNAPSHOT_ID internal xattr exists only on the esnap clone. - Clean up any esnap IO channels on a blob that is no longer an esnap clone due to snapshot creation or removal. See the diagrams and description in blob_esnap_clone_snapshot() in blob_ut.c for details.
