I lurk on the list and didn't comment last time but there is one aspect
of this patch that I think is "bad" style. The function declaration =
should
not be on the same line with the type. Why? Try to find the file where =
a
function is defined instead of used. If you grep "^funcname" you'll =
find
it quite simply. The same is true in YFE (mine being vi) /^funcname =
gets
me there in one shot.

This may not seem an important thing but when you are coming into a
project cold and don't know how anything works or where it lives it
can be very important. Consider trying to find where some common
function from a library is defined in a project with sever 1000 files.

I now return you to your regularly scheduled programming.

Subject: [PATCH] whitespace cleanups for fs/cifs/file.c



Hi Steve,

A while back I submitted a previous version of this patch and got a =
bunch=20
of good feedback from people on LKML and elsewhere. I believe I cleaned =
up=20
the issues they reported and I've now updated the patch for 2.6.11 and=20
resubmit it to you for potential inclusion.

A lot of the changes are arguably a matter of style and preference, but =

since several different styles are used in the code I've tried to at =
least=20
make it consistent. There should be no actual impact on the generated=20
object file from this, merely changes to make it more readable to the=20
human eye, more grep friendly, and slightly more adherent to the =
80chars=20
pr line rule... I never got a clear ACK/NACK from you on this patch, =
but I=20
see that a few of the changes in the previous version are in 2.6.11 - =
it=20
would be nice if you could send me an ack/nack on this one, if you =
don't=20
want these changes I might as well drop it. I've cut this patch on top =
of=20
the one I send a few hours ago with the fix for the copy_to_user =
warning,=20
hope that's OK.

There are still some cleanups to be made in fs/cifs/file.c . There are=20
some unnessesary casts that can go the way of the Dodo (I believe Domen =

Puncer is working on those - need a hand there Domen?), and there are =
also=20
a lot of unnesssary if (foo) kfree(foo); constructs - since kfree()=20
deals fine with NULL pointers, a lot of those can go as well. I've not=20
included such changes in this patch to nut mix things up and keep this =
one=20
about whitespace changes only, but if you are interrested in such =
further=20
cleanups I'll get to work and submit patches to you.
