Okay, I see. So that is probably also the reason for the reimplementation of unmap_kernel_range in the zsmalloc module :) > So my opinion is remove zsmalloc module build and could recover it with > making unmap_kernel_range exported function after we merged it into > mainline. Sounds reasonable, I update the patch to only allow zsmalloc to be built-in. The benefit is that this still allows to use unmap_kernel_range() in the driver.
