Fixed In Version:	ceph-18.2.1-6.el9cp	Doc Type:	Enhancement
Doc Text:	.Improved `rbd_diff_iterate2()` API performance Previously, RBD diff-iterate was not guaranteed to execute locally if exclusive lock was available when diffing against the beginning of time (`fromsnapname == NULL`) in fast-diff mode (`whole_object == true` with `fast-diff` image feature enabled and valid). With this enhancement, `rbd_diff_iterate2()` API performance is improved, thereby increasing the performance for QEMU live disk synchronization and backup use cases, where the `fast-diff` image feature is enabled.
