From 74021bc497c8e8a1b03d633656aa5ff7112bd721 Mon Sep 17 00:00:00 2001 From: Eric Blake Date: Wed, 1 Jun 2016 15:10:04 -0600 Subject: block: Switch bdrv_write_zeroes() to byte interface Rename to bdrv_pwrite_zeroes() to let the compiler ensure we cater to the updated semantics. Do the same for bdrv_co_write_zeroes().
