From 8dc88ac68df89851488a60b8f1582fe466f41a64 Mon Sep 17 00:00:00 2001 From: Andreas Gruenbacher Date: Thu, 23 Jan 2020 19:19:38 +0100 Subject: [PATCH] gfs2: Report errors before withdraw In gfs2_rgrp_verify and compute_bitstructs, make sure to report errors before withdrawing the filesystem: otherwise, when we withdraw first and withdraw is configured to panic, we'll never get to the error reporting.
