[LTP] [PATCH v2 12/31] testcases: sysfs: Add sys_ata01

[Petr Vorel]

Hi Cyril,

> A test for /sys/class/ata_device/*/* files.

Lol, on one of my system I don't have /sys/class/ata_device/,
but I have /sys/class/scsi_device/ directory. I suppose SCSI is still used but
obsolete right? Or would it be worth to test it as well?

Please, before merge change to:
- * - dma_mode, pio_mode and xfer_mode, when non-empty, start with the "XFER_"
+ * - dma_mode, pio_mode and xfer_mode, when non-empty, start with the ``XFER_``

otherwise sphinx complains:
_static/tests.rst:45958: ERROR: Unknown target name: "xfer". [docutils]

Otherwise LGTM, nice test, great patchset.

Only to this particular patch:

I try to have look on the whole patchset tomorrow.

Kind regards,
Petr
