There are couple of tests in shared directory which really should be made generic, so move it. It is mostly collapse range tests, which really can be generic to make super we test every file system which adds collapse range support. Here is what we're moving in this commit. shared/001 -> generic/021 shared/002 -> generic/022 shared/003 -> generic/012 shared/004 -> generic/016 shared/005 -> generic/017 shared/218 -> generic/018 shared/305 -> generic/019 Signed-off-by: Lukas Czerner <lczerner@redhat.com> Reviewed-by: Dave Chinner <dchinner@redhat.com> Signed-off-by: Dave Chinner <david@fromorbit.com>
