Doc Text:	.Object map for the snapshot accurately reflects the contents of the snapshot Previously, due to an implementation defect, a stale snapshot context would be used when handling a write-like operation. Due to this, the object map for the snapshot was not guaranteed to accurately reflect the contents of the snapshot in case the snapshot was taken without quiescing the workload. In differential backup and snapshot-based mirroring, use cases with object-map and/or fast-diff features enabled, the destination image could get corrupted. With this fix, the implementation defect is fixed and everything works as expected.	Story Points:	---
