From: Aneesh Kumar K.V <[email protected]> commit 67476656febd7ec5f1fe1aeec3c441fcf53b1e45 upstream.
This move the dependency to DEV_DAX_PMEM_COMPAT such that only if DEV_DAX_PMEM is built as module we can allow the compat support. This allows to test the new code easily in a emulation setup where we often build things without module support.
