1. A computing device, comprising: a virtual disk comprising a first layer including a virtual disk offset range, and a second layer including an overlapping virtual disk offset range corresponding to the virtual disk offset range; and an input/output (I/O) handling mechanism configured to handle I/O of a meta-operation that manipulates data of the virtual disk concurrent with servicing virtual disk read and write I/O of the virtual disk by allowing at least one meta-operation write to the virtual disk offset range concurrent with a virtual disk write to the overlapping virtual disk offset range.
