From 2e7be9db125a0bf940c5d65eb5c40d8700f738b5 Mon Sep 17 00:00:00 2001 From: Dāvis Mosāns Date: Sat, 5 Feb 2022 20:48:23 +0200 Subject: btrfs: send: in case of IO error log it Currently if we get IO error while doing send then we abort without logging information about which file caused issue. So log it to help with debugging.
