From e192179bb2c080f0130a7ff427c2572909fc31ed Mon Sep 17 00:00:00 2001 From: Vladimir Sementsov-Ogievskiy Date: Wed, 6 Oct 2021 15:17:15 +0200 Subject: [PATCH] block-backend: convert blk_co_copy_range to int64_t bytes Function is updated so that parameter type becomes wider, so all callers should be OK with it. Look at blk_co_copy_range() itself: bytes is passed only to blk_check_byte_request() and bdrv_co_copy_range(), which already have int64_t bytes parameter, so we are OK. Note that requests exceeding INT_MAX are still restricted by blk_check_byte_request().
