Host-based transfer of input-output operations from kernel space block device to user space block device

A method comprising:

• generating a user space block device;
• generating a kernel space block device corresponding to the user space block device;
• receiving an input-output operation at the kernel space block device from an application executing on a host device;
• transferring the input-output operation from the kernel space block device to the corresponding user space block device;
• and
• submitting the input-output operation to the at least one storage system based at least in part on the user space block device;
• wherein the method is implemented by the host device, the host device comprising a processor coupled to a memory.

A computer program product comprising a non-transitory processor-readable storage medium having stored therein program code of one or more software programs, wherein the program code, when executed by a host device comprising a processor coupled to a memory, causes the host device:

• to generate a user space block device;
• to generate a kernel space block device corresponding to the user space block device;
• to receive an input-output operation at the kernel space block device from an application executing on the host device;
• to transfer the input-output operation from the kernel space block device to the corresponding user space block device;
• and
• to submit the input-output operation to the at least one storage system based at least in part on the user space block device.
