[PATCH 1/2] fs: aio ioprio add explicit block layer dependence

From: adam . manzanares
Date: Mon Jun 04 2018 - 14:00:23 EST


From: Adam Manzanares <adam.manzanares@xxxxxxx>

Previously, the ioprio_check_cap function was only defined when CONFIG_BLOCK
was set. Make this relationship explicit and add a stub for !CONFIG_BLOCK.
