feature-removal-schedule.txt is getting out of date again

[Robert P. J. Day]

  yes, i realize i'm sounding like a broken record but, once again,
Documentation/feature-removal-schedule.txt is slipping out of date WRT
items that are now slightly, if not noticeably, behind schedule for
removal.

IIRC I saw few patches addressing some items but they are not yet Linus'
tree, i.e. old mxser driver removal:

http://lkml.org/lkml/2008/1/18/235

Jiri, I see that old mxser removal has been on removal list for a long time
and that Alan has reviewed the whole patch series (+ all patches look good
for me from quick skimming through them).  It also has been in the last -mm
release.  Because we are going to hit 2.6.25-rc1 quite soon I think that
this patch series should find its way into Linus' tree

Andrew, are you going to push it soon (or maybe Jiri should prepare git tree
and send Linus a pull request)?

Robert, I suggest that you just send patches removing outdated items (probably
starting with the one below like you tried in the past) and be quite stubborn
about it (otherwise you can be pretty sure that nothing will happen)...

...
What:   PCMCIA control ioctl (needed for pcmcia-cs [cardmgr, cardctl])
When:   November 2005
....

http://lkml.org/lkml/2007/5/1/107

Christoph, 10 months later and this method doesn't seem to work.

How's about disabling it in -mm and waiting for complaints instead
(if none come just remove the code in 2.6.26-rc1)?

[ Either this or we should just remove the item in question from
  feature-removal-schedule.txt. ]

Thanks,
Bart

I had pinged people about a week ago on lots of these items, for the
most part patches are staged and going in through various trees, let's
wait for rc1 and see what has landed by then.

OK, great to see that it is being dealt with.

ah, i had no idea that things were in the pipeline.  that's always
good to know but, still, it's not a bad idea to keep the info in the
features removal file as least *vaguely* up to date.  at the very
least, if something seems to be more than a year behind schedule for
removal, then a small addendum to that item in that file by way of
explanation might be in order.

A quick summary of what I've been tracking, some have already gone in,
but I'll wait for rc1 to do a pass over all this and send out a summary.

What: CONFIG_FORCED INLINING:
-removal patch being tested in x86.git, upstream unlikely for 2.6.25,
not a big deal to wait for 2.6.26

This has been done and is currently in scsi-misc awaiting for a pull.

Well the in-kernel callers have not all been converted yet. I have
actually done the work, but it needs testing and merging by maintainers.
Getting it done during this merge window would be nice, I'm going to
try to make that happen after I get back from LCA. Otherwise probably
2.6.26.

Stephen Hemminger sent a removal patch to Jeff, it probably was too big
for the mailing list.

GregKH: This is queued up in my tree to go to Linus, see my previous
post on
lkml and the linux-usb mailing list about this topic.

Still some users in-tree, some discussion happening on how to get this
finished.

yes, i didn't see any followup on that item.  i still have the patch,
unless it's already working its way thru the system.
