From d4c27348751bffeb57d87fc631f76716e3036c6d Mon Sep 17 00:00:00 2001 From: Jie Liu Date: Thu, 24 Jul 2014 18:40:43 +1000 Subject: [PATCH] xfs: fix error handling at xfs_bulkstat From: Jie Liu We should not ignore the btree operation errors at xfs_bulkstat() but to propagate them if any. This patch fix two places in this function and the remaining things will be fixed with code refactoring thereafter.
