Try to avoid links to external pages (specially if they are only 2 lines :-).

Seems like keyword shouldn't use __attribute__((nonstring)), so this looks right.

Hi Harshit,
Another two nitpicks:
* Since this is the second version of the patch, write "[PATCH v2]" in the title instead; that way people know you have sent an earlier version. On top of that, you should explain the differences between each version after the "---" line (i.e. the part that does not belong to the commit message).
* You may want to write down who you CC'd (e.g. Tony and the stable mailing list) in "Cc: ..." lines before the Signed-off-by line.
Thanks for the patch!
Hope that helps, Miguel
