The patch below adds a comment about why it is safe to use in_atomic() in
scst_cmd_atomic() -- the 2.6.29 checkpatch script issues a warning about it.
At the same time, the scst_cmd_atomic() comment has been converted to
kernel-doc style. See also Documentation/kernel-doc-nano-HOWTO.txt for more
information.
