From e8f5b395d5332b5d720d62d33d6e06836392fd85 Mon Sep 17 00:00:00 2001 From: David Sterba Date: Thu, 13 Jul 2017 17:42:15 +0200 Subject: [PATCH] btrfs: btrfs_create_repair_bio never fails, skip error handling As the function uses the non-failing bio allocation, we can remove error handling from the callers as well.
