kernel 2.4.14 compiling fail for loop device

[Terminator]

I tried to compile 2.4.14 with loop back device as kernel module, and
got the following error. It seems it's removed from

Nope, it was added post-pre8 to final.  The deactivate_page function was
removed completely.

Safe to remove those two lines from loop.c? Other calls of deactive_page 
were just removed it seemed.

Yes, it is.  I am sure that will be exactly what 2.4.15-pre1 does.

This is why 2.4.14 should've been 2.4.14pre9!  

I thought Linus was going to keep the changes from pre to final to a
minimum.  Actually, I don't think there should be *any* difference between
the last pre and the released kernel...

Look, Linus.  Things should _not_ happen this way.

Why do we add non-trivial changes when going from last -preX of a test kernel
series to -final?

Please make the last stable -preX the -final _without_ any changes.  This is
the third time this caused problem in recent times (2.4.11-dontuse, parport
compile problems and now loop.o), and why don't we learn from previous
mistakes?

Isn't it stupid that some tarballs in the /pub/linux/kernel/v2.4/ do not even
compile, while those in /pub/linux/kernel/testing/ does?

You'd almost expect this from XP-beta to XP-final, but not Linux kernel...

	No, there was a different problem that required hand patching.

	linux-2.4.14-pre8 did not compile either if rd.o or loop.o
were compiled as modules, but the names were changed to protect the
guilty (different symbol name, one that wasn't exported).

	Maybe there should have been another -pre.  But the only reason
I was staying on top of the -pre kernels was because I had several major
changes in there, this time around.

	-pre7 actually did compile.  -pre8 did not (not without adding
a line to ksyms.c).

Few points.

- I don't believe that there is any such thing stable enough to be caled
  XP-final, or even XP-beta ;)  Specially when compared to the Linux kernel
  standards of stability.

- It is not necessary to compare linux with other low grade software ;)
  They may not work.  But linux do.

- I nevey use nor plan to use XP so I don't care if it doesn't work.

I couldn't, too ;)

[David Lang]

linus goofed when he missed the two refrences to this function.

however as he pointed out earlier it was a function that could never get
called.

removing a function that can never be called comes pretty close to a
trivial change to me.

even with this mistake it far fewer changes then we have seen in some of
the past -final releases so at the very least it's a step in the right
direction.

if you try to compile it modular, the "make modules" will work, but
the "make modules_install" will choke after copying the modules under
/lib/modules when it tries to run the final "depmod" at the end.

so, yes, i'm curious -- how did he get a final kernel and modules
without removing those lines?

When I did, and used a looped an iso image, eventually my
computer froze up.  Using the actual cd, it did not.  So my
personal answer would be no.

when mounting an EFS cd on the loop it also froze. this is _without_
removing the lines. the same happens when I miunt an efs partition from
harddrive with -o loop. also crash. sometimes early. sometimes late.

I got a kernel and modules without removing those
lines - it complains at depmod, but the kernel and
modules do build and install -

I didn't ever boot to that kernel since the warning
bothered me, and I fixed the source and recompiled
before booting into 2.4.14 -
