From e7e588d432d31ecebc26358e47201dd108db964c Mon Sep 17 00:00:00 2001 From: Hanna Reitz Date: Mon, 11 Oct 2021 17:50:31 +0200 Subject: qcow2: Silence clang -m32 compiler warning With -m32, size_t is generally only a uint32_t. That makes clang complain that in the assertion assert(qiov->size <= INT64_MAX); the range of the type of qiov->size (size_t) is too small for any of its values to ever exceed INT64_MAX. Cast qiov->size to uint64_t to silence clang.
