From 0383ad4374f7ad7edd925a2ee4753035c3f5508a Mon Sep 17 00:00:00 2001 From: Ming Lei Date: Fri, 29 Mar 2019 15:07:54 +0800 Subject: block: pass page to xen_biovec_phys_mergeable xen_biovec_phys_mergeable() only needs .bv_page of the 2nd bio bvec for checking if the two bvecs can be merged, so pass page to xen_biovec_phys_mergeable() directly. No function change.
