Signed-off-by: Eryu Guan --- This fio job file has been proven to be potent, it triggers WARNINGs on ext4 and xfs with 4.1-rc6 kernel. ext4: WARNING: at fs/ext4/inode.c:1328 xfs: WARNING: CPU: 7 PID: 3090 at fs/xfs/xfs_file.c:726 xfs_file_dio_aio_write+0x176/0x2a8 [xfs]() The ext4 issue should be fixed by Lukas's patch ext4: fix reservation release on invalidatepage for delalloc fs And it ever paniced kernel in mm code and hung xfs. I reduced the numjobs and iodepth to reduce the test time(~25s on my test host) and scale them by $LOAD_FACTOR. And it still could trigger the warning on ext4 and xfs with reduced workload. v2: - use mktemp to create tmp fio job file v3: - initialize scratch dev and mount it correctly before test - roll back to use /tmp/$$ as tmp tests/generic/090 | 122 ++++++++++++++++++++++++++++++++++++++++++++++++++ tests/generic/090.out | 2 + tests/generic/group | 1 + 3 files changed, 125 insertions(+) create mode 100755 tests/generic/090 create mode 100644 tests/generic/090.out diff --git a/tests/generic/090 b/tests/generic/090 new file mode 100755 index 0000000..e7cca52 --- /dev/null +++ b/tests/generic/090 @@ -0,0 +1,122 @@ +#! /bin/bash +# FS QA Test generic/090 +# +# Concurrent mixed I/O (buffer I/O, aiodio, mmap, splice) on the same files +# +#----------------------------------------------------------------------- +# Copyright (c) 2015 Red Hat Inc.
