Not, unless you describe the problem in more details:
- kernel version
- applied patches
- command line and output of gcc
...

 2)input: "sh patches -j /home/guozl_1/linux-2.4.4-2002-10-06"
 3)linux kernel is :linux-2.4.4
 4)  Cross compile is MontaVista Hothard 2.0 for ppc platform
 5) make vmlinux:

All three are a bit dated and likely noone has ever tested that
combination before.
Can you upgrade to something more current? kernel 2.4.21-pre5 should
work out of the box, I would guess.

There is little point in fixing a problem _again_. :)

Don't know, didn't look at the code. But it appears as if
recalc_sigpending has been changed sometime and one of 1), 2) and 3)
has the new version and another one the old one. Just a guess.

If you want to fix it yourself, look at fs/jffs2/background.c and
search for recalc_sigpending in http://lxr.linux.no/ . But upgrading
sounds like the better option.

thanks for you answers.

I decide to not use mtd_cvs_20020612.tgz.
only use linux-2.4.4.

thanks.

Look at the macro recalc_sigpending(). It should be fairly obvious.

If you can reproduce it with the current code in 2.4.21-pre then I'll
care. With 2.4.4 and JFFS2 from that date your compilation error is
probably the least of your worries.
