Re: [PATCH 0904/1285] Replace numeric parameter like 0444 with macro

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



In general, I find sending 1285 patches to lkml unfriendly without doing a
precheck if the general idea is good.
This is especially true as you did NOT provide a cover letter that would
allow to hide this thread on lkml.


Regarding this particular patch, I do not really like this change, as I find
"0444" much easier to parse than "S_IRUSR | S_IRGRP | S_IROTH"
