It's used to stop unmount retrying forever when it hit IO error. This case try to unmount an faulty dm device, and to sure unmount won't retry forever if fail_at_unmount=1. Signed-off-by: Zorro Lang --- Hi, Nothing changed in this V3. Due to I modify [PATCH v3 1/2], so I think if I send this 2/2 patch with 1/2 together, maybe easy to review and merge? :) Thanks, Zorro tests/xfs/006 | 81 +++++++++++++++++++++++++++++++++++++++++++++++++++++++ tests/xfs/006.out | 2 ++ tests/xfs/group | 1 + 3 files changed, 84 insertions(+) create mode 100755 tests/xfs/006 create mode 100644 tests/xfs/006.out diff --git a/tests/xfs/006 b/tests/xfs/006 new file mode 100755 index 0000000..c134b1c --- /dev/null +++ b/tests/xfs/006 @@ -0,0 +1,81 @@ +#! /bin/bash +# FS QA Test 006 +# +# Test xfs' "fail at unmount" error handling configuration.
