There is a thread in progress on the user's list about this issue:
http://www.beowulf-underground.org/pipermail/pvfs2-users/2008-January/002307.html
I think the summary is that you may be able to get away with this?
- make distclean
- configure
- manually clear the HAVE_KERNEL_DEVICE_CLASSES flag in pvfs2-config.h
- make
-Phil

Hello
Is there any outstanding problem reports on using the kernel module in
the latest Red Hat EL4 kernel.
I'm running linux-2.6.9-67.0.1-ELsmp on an Intel Core 2 duo, but cannot
get the kernel module. Unfortunately, I've never used the kernel module
before so I don't have much expertise in this area. While building I
got a bunch or warnings like (the build log is attached):
CC [M] /root/pvfs-2.7.0/src/kernel/linux-2.6/devpvfs2-req.o
/root/pvfs-2.7.0/src/kernel/linux-2.6/devpvfs2-req.c: In function
`pvfs2_dev_init':

`pvfs2_dev_cleanup':
/root/pvfs-2.7.0/src/kernel/linux-2.6/devpvfs2-req.c:1050: warning:
implicit declaration of function `class_device_destroy'
and on the install I get the following:
Building modules, stage 2.
MODPOST
*** Warning: "class_device_destroy"
[/root/pvfs-2.7.0/src/kernel/linux-2.6/pvfs2.ko] undefined!

install -m 755 src/apps/kernel/linux/pvfs2-client-core
src/apps/kernel/linux/pvfs2-client /opt/pvfs-2.7.0/sbin
And then when I try to install the mod, I get the dmesg output:
pvfs2-set-debug[32686] trap divide error rip:b2c9e9 rsp:ffffd2cc error:0
pvfs2-set-debug[32687] trap divide error rip:b2c9e9 rsp:ffffd2cc error:0
pvfs2-set-event[32689] trap divide error rip:b2c9e9 rsp:ffffd2cc error:0
pvfs2: Unknown symbol class_device_destroy
pvfs2: Unknown symbol class_device_destroy
My guess is I need to hit a config flag, but I don't know which one to
check.
Cheers,
Brad
