Subject: percpu_counter_mod not getting into SMP kernel image when ext2/3 compiled as modules
Date: Mon, 10 Nov 2003 15:30:06 -0800 [thread overview]
Message-ID: <3FB01F7E.7090100@houseofdistraction.com> (raw)
In 2.6.9-test9 (also tried with bk15) I have ext2 and ext3 both
configured as modules. When I do "modprobe ext3" it says:
FATAL: Error inserting ext3
(/lib/modules/2.6.0-test9-bug-t1/kernel/fs/ext3/ext3.ko): Unknown symbol
in module, or unknown parameter (see dmesg)
and dmesg says:
ext3: Unknown symbol percpu_counter_mod
I found one message in the archive
(http://www.ussg.iu.edu/hypermail/linux/kernel/0310.2/0311.html) which
mentions this problem and includes a proposed fix. The lines from the
this proposal made it into lib/percpu_counter.c but somehow it seems
that they are not causing the symbol to end up in the main kernel
image. In fact the string "percpu_counter_mod" does not occur in
vmlinux or in any of the modules other than ext2.ko and ext3.ko.
The kernel in question was compiled with gcc 3.3.1 on an up-to-date
debian/unstable. A copy of the exact .config I used can be had from
http://jlb.changelog.com/config-2.6.0-test9-bug-t1
