Hi Bartosz

This response below is the same as another email thread

Personally, I prefer 4 digit octal in most cases as it
shows the coder knows that the argument is a permissions
use and not just some generic 0.

There are not many uses of 0 for permissions outside of
module_param*.

I suppose all the variants of module_param calls, as a
0 there is specifically a "not to appear in sysfs" flag,
could or should be excluded from that octal test.
