Wong" , Eryu Guan , David Howells Return-path: Sender: owner-linux-mm@kvack.org List-Id: linux-ext4.vger.kernel.org v4: respin set based on Eryu's comments These tests are companion tests to the patchset I recently posted with the cover letter: [PATCH v6 00/20] fs: enhanced writeback error reporting with errseq_t (pile #1) This set just adds 3 new xfstests to test writeback behavior. One generic filesystem test, one test for raw block devices, and one test for btrfs. The tests work with dmerror to ensure that writeback fails, and then tests how the kernel reports errors afterward. xfs, ext2/3/4 and btrfs all pass on a kernel with the patchset above. The one comment I couldn't really address from earlier review is that we don't have a great way for xfstests to tell what sort of error reporting behavior it should expect from the running kernel. That makes it difficult to tell whether failure is expected during a given run. Maybe that's OK though and we should just let unconverted filesystems fail this test? Jeff Layton (5): generic: add a writeback error handling test ext4: allow ext4 to use $SCRATCH_LOGDEV generic: test writeback error handling on dmerror devices ext3: allow it to put journal on a separate device when doing scratch_mkfs btrfs: make a btrfs version of writeback error reporting test .gitignore | 1 + common/dmerror | 13 ++- common/rc | 14 ++- doc/auxiliary-programs.txt | 16 ++++ src/Makefile | 2 +- src/dmerror | 44 +++++++++ src/fsync-err.c | 223 +++++++++++++++++++++++++++++++++++++++++++++ tests/btrfs/999 | 93 +++++++++++++++++++ tests/btrfs/group | 1 + tests/generic/998 | 64 +++++++++++++ tests/generic/998.out | 2 + tests/generic/999 | 77 ++++++++++++++++ tests/generic/999.out | 3 + tests/generic/group | 2 + 14 files changed, 548 insertions(+), 7 deletions(-) create mode 100755 src/dmerror create mode 100644 src/fsync-err.c create mode 100755 tests/btrfs/999 create mode 100755 tests/generic/998 create mode 100644 tests/generic/998.out create mode 100755 tests/generic/999 create mode 100644 tests/generic/999.out -- 2.13.0 -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
