After doing some things on a small issue,
I noticed through web surfing, that there were patches
submitted pertaining that __initcall is deprecated,
and device_initcall should be used.
Where was this discussion? Do you have any pointers to it?
The best info on this is scripts/checkpatch.pl
when I found this I just did a quick search of __initcall
(which gives hits here and there)
(also found others at around 2008 or so)
Thanks. IMO there should be something in the kernel source tree
that says explicitly that __initcall is deprecated and should be
replaced by using<whatever should be used>. That's missing.
I should of searched the source tree for something
that says deprecated and so forth before doing anything(the
checkpatch.pl was something I noticed down the line but doesn't say
I don't see any mention of __initcall being deprecated in
Linus' mainline git tree, or in linux-next, or in mmotm.
Where are those patches?
I don't know(I'm out of the social pipeline when it comes to Linux news,
like in the explanation part of the patch
I was looking into something else, then ran into this,
so as a break(from what I was originally doing)
decided to do this and submit.
So as a change of subject(since what I was looking at
was frustrating me),I decided to grep the whole tree
and make the change(partially).
Currently I'm running this patch on my system, kernel compiles
without any errors or warnings.(thought there would be a speed increase
but didn't see much(if any)).
No, __initcall(x) is just a shorthand version of typing
device_initcall(x). They do the same thing.
yep, that's what I found out as well(reason for the cosmetic
in the subject line).
Biggest problem I have though is testing this on other hardware types
(I only have a macbook,and an iMac).
So please if you have the access to other arch/hardware types please
Now what I mean by partially is the __initcall function is still
there, so(if any) userspace apps/libs depend on this it's there
so they dont break and/or any other subsystem, that needs time
to make the changes.
The only thing that might be affected is building out-of-tree drivers,
but those are easy to fix.
alright..main concern is making sure things don't break in the
kernel(even though things do).
I can have a go at the header files, submit
then if it's something people agree they want to do, then they
can go from there(if not it's fine as well).
the remaining files that still have __initcall in them are:
(according to grep)
either I or somebody else, can change this(although a bit
concerned about breaking things).

In any case I'll leave this to you guys to decide.
The patch is in cyberspace now, so if/when this ever
is decided it's there(patch), then can be used then.
