In my review of the earlier patch, I said I was fine with the octal 
constants, but on reflection, I'm not sure it's worth changing them just 
for the hell of it.  We'd probably get a patch from someone else later 
to change it back to symbolic constants.  Is there an actual coding 
style issue, or is this just a personal preference?

Hi Ian

yes its a coding style issue(checkpatch.pl WARN)

Those three lines are unnecessary, especially the initial blank line. 
I'm not sure whether Greg will ask you to fix it up.

It looks like the octal permissions have been blessed from above 
(Linus), so this is good.
