I am very confused about the generation and synchronization of mipmap.

I tried the mipmap generation sample. And after I enable best practice validation layer, I get this warning:

Validation Performance Warning: [ UNASSIGNED-BestPractices-PipelineBarrier-readToReadBarrier ] Object 0: handle = 0x207920c9a40, type = VK_OBJECT_TYPE_DEVICE; | MessageID = 0x1264fdd5 | [AMD] [NVIDIA] Performance warning: Don't issue read-to-read barriers. Get the resource in the right state the first time you use it.

	vkb::insert_image_memory_barrier(
	    blit_command,
	    texture.image,
	    VK_ACCESS_TRANSFER_READ_BIT,
	    VK_ACCESS_SHADER_READ_BIT,
	    VK_IMAGE_LAYOUT_TRANSFER_SRC_OPTIMAL,
	    VK_IMAGE_LAYOUT_SHADER_READ_ONLY_OPTIMAL,
	    VK_PIPELINE_STAGE_TRANSFER_BIT,
	    VK_PIPELINE_STAGE_FRAGMENT_SHADER_BIT,
	    {VK_IMAGE_ASPECT_COLOR_BIT, 0, texture.mip_levels, 0, 1});```

I think this is because :transfer "TRANSFER_READ" to "SHADER_READ". Is there a way to eliminate the warning? Or I can I completely ignore it？
