[PATCH 3/6] ps3disk: replace flush_kernel_dcache_page with flush_dcache_page

From: Christoph Hellwig
Date: Mon Jul 12 2021 - 02:12:08 EST


Pages passed to block drivers can be mapped page cache pages, so we
must use flush_dcache_page here instead of the more limited
flush_kernel_dcache_page that is intended for highmem pages only.
